- People who think artillery is a Game Breaker versus those who think it's Acceptable Breaks from Reality due to its unique top-down view when in sniper mode, immense firepower combined with a high chance of hitting the top armor, the weakest point of any tank, and decent accuracy even from across the map, often hitting tanks which are slowly moving or not moving at all.
- Since the early days of the Closed Beta, artillery accuracy, penetration, splash damage, shell travel times, and accuracy penalties for moving have all been nerfed, and some people still think they're overpowered.
- Artillery can be infuriating for those who do not understand that their purpose is to introduce a new threat to being spotted - getting OHK'd for taking inadequate cover. Artillery vehicles are (supposed to be) worthless as anything but extremely long-ranged glass cannons adding firepower to a forward team - and their existence as such gives worth to Mediums and Lights as both scouts and as artillery-killers.
- Artillery is also a serious point of contention on the forums (at the very least, on the North American ones). A large sect of the American Server Cluster outright wants Artillery removed from the game, and shows no intention of ceasing until it's been deleted outright. A vast majority of the American players who complain are the upper echelons of the game's statistics. The fact that they complain means they're doing it's job.
- And not only that, the NA server seems to simply be the most Anti-Artillery server. The EU server is overall neutral, and the RU server loves artillery.
- Also divided between people who think Soviet tanks are overpowered and people who think German tanks are overpowered.
- The Americans seem to have their own base-breaking done. They are either balanced or underpowered.
- Not to mention the influx of complaints against the Soviet T-54, the medium tank that borders on being a player controlled Demonic Spider.
- Add to that the developers' (allegedly) not so hidden anti-German bias — SerB has been on the record with his (semi-joking) quip that "Germanophiles must suffer" — and you get Flame Bait so ripe that it's best touched with at least a ten-foot pole if you have absolutely have to touch it at all.
- The above is typically most exemplified with the way the Tiger I is represented in the game, as the developers have made many ahistorical changes to 'balance' it (among which, weakening the lower front glacis, making the transmission a fire hazard, making the gun mantlet not-spaced armor, etc) which players (especially new players) feel make the tank very underwhelming as it struggles to fill any role outside of a second line sniping tank.
- Tier X Tank Destroyers (particularly the Waffentrager "Waffletractor" auf E-100 and Fv215b "Death Star" 183) are this among the older community, which view these tanks as having far too much of a combination of view range, camo rating, penetration, and damage. The general opinion is that they can do far too much up front (alpha) damage with no drawbacks.
- Autoloader tanks. In real life very few of these designs ever saw mass production because of impracticality. Not so in World of Tanks, where they are all over the place in higher tiers. Instead of firing one shell at a time, they possess a 'clip' of 4-6 shells that can be fired rapidly, at the cost of very long clip reloads. Since these tanks are usually so fast, they are often detested for being able to deal a high amount of damage in a short amount of time and rapidly retreat before they can be counterattacked. It doesn't help that Wargaming has introduced tanks like the Wt. auf E-100 that are basically fictional ala Secret Weapons Over Normandy.
- Beyond even all of that, the "RNG" (Random Number Generator/God, in reference to the game's dispersion) puts several factors outside the player's control. Constant arguing ensues over if this is good for the game or not.
- It even got a Fan Nickname (on Russian servers at least) of GBR, or Great Belorussian Random.
- Nothing splits the base like the test server. A new test server is guaranteed to split the base into two camps: the RU server vs everyone else. This is because RU players have a reputation - deserved - for team-killing everything which has the sheer effrontery to be on the test server without an RU server tag. Explanations for this phenomenon range from nationalism, to a younger Russian playerbase, to a larger Russian playerbase (which leads to proportionately more GIFT), and finally, to a perception on the RU server that non-RU players are The Load. Whatever the reason behind the Russian team-killing phenomenon, it tends to lead to very ugly inter-server wars of words every time a new test is up. Thankfully, as of patch 9.0, TKing on the test server will get you banned on the live server too, which seems to have cut this down a little.
- The "Monthly Challenge" in which you can get a free tank plus garage slot upon completion is so horribly biased in favor of elitist gamers who have no life and plenty of disposable income (Gold for real-life money) that casual gamers will never, ever come close to reaching even the 25% mark. Just to show you how cheap WarGaming is about giving away free tanks with a garage slot:

- Gold Ammunition, especially since being made credit bought, with many players arguing they allow tanks to get out of situations where credit bought ammo simply isn't enough and many others considering it a scumbag move that lets those who use it 'buy skill' rather then bother to try and aim for weak points. This is especially frustrating to the drivers of super heavy tanks such as the Maus and T95 when a player sees them coming towards them and simply load in a HEAT round and blow straight through their armor.
