History YMMV / OrcsMustDieUnchained

** The randomness of trap upgrades. Want to upgrade a trap? Well you better hope points for it drop in a chest. This is somewhat mitigated in later updates, where the chests that drop trap upgrades become much more common, and as you level up the chests you get outside of particular difficulty-tier maps will always drop for the highest difficulty you've unlocked (i.e. if you've unlocked Rift Lord difficulty, you will always get Rift Lord chests for completing daily quests, weekly challenges, Chaos Trials, or daily log-ins). There's also daily deals in the in-game store which allow a player to potentially buy points for one of several random traps or unlock a new trap for skulls.
* TierInducedScrappy:
** Bloodspike, Bionka, and Blackpaw - for simply being ''too good'' at their jobs. When enemy heroes or bosses appear, it's possible for them to chew through their health. (Bloodspike can, if aimed properly, kill enemy heroes in one hit) Because they are more durable than most other characters, they can easily hold off waves, whereas others like Zoey, Cygnus, and Gabriella will die if some creeps even so much as sneeze in their general direction.

** Elementals in general. Earth Elementals, unlike int he previous games, now ignore stunning and slowing effects, so crowd-control traps like Web Spinners, temple Gongs, and Tar are useless against them, and they're resistant to elemental damage, making them hard to kill if you're playing an elemental hero with an elemental loadout. Then there's Fire Elementals, who split apart into Firelings. Unlike in the earlier games, where the Firelings seek out the hero, now they seek out heroes... or they seek out barricades and ''explode'' on them.

* GoddamnedBats: Kobolds and satyrs, who are weak but move ''very'' fast. Tar traps do very little to slow them, and they are very good at bypassing traps.

** It's rather telling that the game includes "Big Game" traps, whose sole purpose is to ''specifically'' target most of the enemy types listed above.

** Front Clan Orcs and Northmun minions, for melee heroes. They don't do much damage, but multiple hits cast the Chilled effect on a target, and if a hero or Guardian gets hit by three or more of them, they'll be frozen in place for a moment. This makes them very tricky for a melee hero to deal with.

** The randomness of trap upgrades. Want to upgrade a trap? Well you better hope points for it drop in a chest.

** The Dwarf Priest mercenary, who generates a barrier that blocks ranged attacks and creates protective shields over other minions. This make shim a nightmare if you have a ranged hero, or if you have a projectile-heavy loadout such as Arrow Walls or Ceiling Ballistas.

** The Unstable Kobold mercenary runs around at high speeds and disables traps and plants spikes in the ground that slow down heroes who run over them. It's also incredibly hard to pin down and kill because of its speed and because traps ignore it.

** The Bouncer Bear mercenary type doesn't do a lot of damage... but he flings any hero he gets into melee range of a very long distance, making him incredibly annoying for melee heroes.

* ComplacentGamingSyndrome: Expect to see waves of kobolds thrown out a lot in survival.

* BrokenBase: The change from the two modes to focusing on just Survival mode initially:
** On one hand, some felt that removing Siege Mode pretty much [[ItsTheSameNowItSucks removed what made this game unique from the previous ones]], even though they did concede that Survival mode was frankly a ''mess'' and that two similar but different modes was a nightmare to balance. What especially did not help was that some heroes like Midnight and Bloodspike seemed to be designed with Siege mode in mind.
** And on the other, others felt that focusing on just one mode was a change for the better. Survival's matchmaking quickly [[UnwinnableByMistake paired people with poor equipment on unwinnable matches]] due to how the matchmaking was handled, and the changes to pure survival allowed the game's gimmick of multiple types of characters to shine out. Others like that they changed Midnight and Bloodspike to make them more appealing in survival mode.
** Then, there was the addition of "Sabotage".

** Maximillian, for the fact that when the waves come, he doesn't contribute very much outside of scratch-damage and dealing combos. His main assets are the fact he can place down lots of traps with his passive that gives him a discount on traps and can slow down enemy creeps. He ''can'' be competitive in later waves, but [[GuideDangIt it requires picking from a fairly limited set of perks]], and [[MagikarpPower requires the other heroes to baby him]].
