History YMMV / PhantasyStarOnline2es

* TierInducedScrappy:
** Weapons with bad [=PAs=], especially bad 3rd Gen [=PAs=]. The most infamous examples are Wired Lance and Bullet Bow; both Kaiser Rise and Million Storm have among the worst DPS and DPP in the game, and unlike niche [=PAs=] like Tears Grid possess little, if any utility whatsoever. 4th Gen did very little to change the meta; most of the bad weapons still have bad [=PAs=] (Holding Current), Dual Blades improved to "somewhat usable" with Kestrel Rampage, and some of the already-great weapons got ''even better'' [=PAs=] (Moment Gale is relatively weak but has massive coverage while Bloody Sarabande's DPS is almost GameBreaker tier).
** Most Tech weapons are niche at best due to Techniques being left in the dust in favor of [=PAs=]. Long story short, game mechanics do not favor Techniques, as the elemental damage of the Technique takes priority over anything else. This makes specializing for certain endgame content difficult, and most Techniques do not have the DPS or DPP to keep pace with top tier [=PAs=] like Slash Rave.

** E-Frames are slowly falling into this, mostly because E is the most common damage type in the game, so practically everyone and their aunt has a solid E-Frame. It's even worse if you get a 12★ whose damage type is E, since they more or less obsolete 11★ E-Frames, making most conventional [=esScratches=] almost useless to play outside of the Seasonal 12★ and some Photon Arts and Techniques.

** As of the release of 3rd Generation [=PAs=], this effect has mostly evened out with a wider variety of top tier weapons. Gunslashes (ironically), Jet Boots, and Twin Daggers remain the most common weapons, but other contenders include Double Sabers, Assault Rifles, and Knuckles.

* GameBreaker: Out of all the Chips in the game, none are more extreme than the humble yet insanely powerful Solid Straight. What appears to be your average freebie 11★ Chip turns into a terrifying monster of a Chip when fully powered, starting from a mediocre 19 Cost 110%/120% U Frame to an almighty ''13 Cost 210%/220% U Frame'' after Plugs 1 and 3 are maxed out. His low cost and exceedingly high multiplier make him one of the strongest slot fillers in the game with among the highest DPC ratios of any Chip, completely obsoleting nearly every other slot filler and 11★ in the game. He's one of the few Chips to have the honor of having a FanNickname: [[ExactlyWhatItSaysOnTheTin "baseball"]].

** El Dagans. Fast, extremely aggressive, tankier than regular Dagans, and anything they do will chew through your health at an insane rate. They also tend to attack in groups of two or more, if one wasn't enough.
** Regular Dagans are also rather fearsome due to possessing a fast claw attack that has disproportionately high damage. On EX Quests, one quick swipe can deal over '''1000''' damage.
** El Ahdas are like El Dagans, but have even more health and more irritating and stronger attacks. Thankfully, unlike El Dagans, they also tend to attack one at a time, though they're usually accompanied by other mooks.

* GameBreaker:
** Spread Needle is basically a better Missouri with a chase bonus that boosts the effects of chase damage. Pair with one of the two Seraphy Illustration Chips for maximum damage shenanigans.
** Yamigarasu is a high damage status damage booster that is a combination of a better Saga (+180% damage vs. status afflicted enemies) and a status affliction Chip. She is the strongest Chip in her category due to status damage Chips simply not being common.
** Elder Rebellion has a massively broken power-to-cost ratio, practically infinite range, and is the only attack that can be cancelled mid-animation via swiping, which performs Stylish Roll, a slow-motion dodge that has a ton of invincibility and performs a normal attack that restores your PP in the process. Twin Machineguns by extension are also this due to having the fastest rate of attack in the game, allowing them to easily proc Passives with Low activation rates.
** [[Anime/PhantasyStarOnline2TheAnimation Rina [Premium]/SORO [S Premium[=]=]]] grants a 60-second duration during which you gain a gradually-increasing damage buff that caps out at +180% after 18 seconds. While not game-breaking on her own, she possesses a damage type that no other Chip has, allowing her to ''stack with other {{Game Breaker}}s'' '''multiplicatively'''.
** Diffuse Shell can hit insanely hard by normal standards. It's possible to hit 999,999 for two hits in a row in one cast.
** Elder Rebellion has since been [[PowerCreep power creeped]] by Facet Folia. Close ranged, but hits a ''ridiculous'' number of times while having invulnerability throughout the animation, making it both extremely safe to spam and insanely powerful. Higher-end builds commonly see '''six digit hits''' with this Art, and if you have a really good build with Nesis Arion, you can '''''hit the damage cap''''' on most of the hits!
** Darker Busters [Anniversary] was actually bad enough that even the Japanese playerbase complained about SEGA cashgrabbing on 48 Hour Limited Scratches. It's a D-Frame/Chase chip that gives a whopping ''130%/135% D-Frame to all elements'' and 70% Chase, which stacks up to 3.9x/3.995x innate, making it one of the single strongest solo Chips in the game. This doesn't even account for the fact that since D Frame is relatively rare, you can sub in Darker Busters [Anniversary] into nearly any deck. Darker Busters is so overpowered, in fact, that even in the era of 13★ Chips, it remains practically the best 12★ in the game, and when teamed up with a 13★ Chip utterly destroys Extra Hard difficulty bosses.
** 13★ Chips in general, which are designed to be PurposefullyOverpowered. 13★ Chips possess obscenely high multipliers that are far and beyond higher than anything else in the game, can be double Released and soar to a maximum Level cap of 90, which makes them incredibly potent on the raw stats side, and possess a tier-standard effect that halves the Cost of Photon Arts and Techniques equipped in the same Deck as it as a way to offset their egregiously high Cost.

** Late September Eternal Tower had 97F~99F, which is notorious for being a massive BeefGate due to the return of Dirandals and Sol Dirandals, who are [[BossInMooksClothing somehow tougher than bosses]] encountered earlier in the Tower and will obliterate you in seconds if you don't take the time to evade or keep them stunlocked.

* MostWonderfulSound:

* ThatOneLevel: Eternal Tower 5 (April/May 2018) had Block 97F-99F, which is near-universally considered the worst Block in the entire Tower. The Block is largely proliferated with Sanctum Dragonkin, which include [[ShieldBearingMook Sadinians]] and [[ChargeAttack Dirandals]], both of which are seen as DemonicSpiders due to their overinflated HP and tendency to kill you extremely fast if you make a mistake. The former are also very annoying to kill due to their shields blocking a majority of your hits, while the latter abuse a ram attack that gives them [[ImmuneToFlinching super armor]] and usually kills in one or two hits.

* GoodBadBugs: The mid-March 2017 story update accidentally gave Ragne Units a chance to drop with Gift Receptor during the Dark Agrani EQ. While this doesn't do anything on its own, the Units can be sent to ''VideoGame/PhantasyStarOnline2'' and used in Affixing to transfer Lucky Rise I from the Units found in the Excube Shop to other Units. SEGA implemented a hotfix to eliminate the bugged Units.

** 13★ Ares Kaiser, who is partly designed to be PurposefullyOverpowered. In the SP Slot, she has a maximum multiplier of '''400% E-Frame''', which is almost twice as high as any 12★ E-Frame in the game. Not only that, but if paired with a compatible Link Chip, she also buffs your maximum Light Attribute by 20%. In addition, as a 13★, she has a tier-standard effect of ''halving'' the Cost of all compatible Photon Arts and Techniques equipped in the same Deck as her.

** 12★ Aurora. Her chase buff is complete garbage, being outpaced by ''10★s'', and her secondary effect of adding extra damage is completely useless due to the damage addition being a flat number.
