In order of annoyance
No fire/attack bug for FT - Happens exactly when you need it not to happen the most. Have died way too many times because of it. I refuse to unlearn my decades of muscle memory because the game is bugged
Children - Too many children play this game. I wish any game rated M should legally be required to authenticate/verify age through the use of a credit card. Does not promise a stop, but at least is a deterrent that would filter out a good chunk.
Game performance - Having to lower graphics to the point that it looks like an outdated 20 year old game in order to get a semi decent performance on high end hardware that plays every other game on high graphics like a charm.
Collision bugs - Getting stuck in places have cost me a good amount of matches. Happens more often as Pred but FT as well
Predator gameplay - So many things are just half-ass baked. Leaping mechanism is not accurate, you either don’t actually land where the waypoint is or you bump into a branch on your way or you bump into a rock and do a vertical leap. Crosshairs are OFF, like way OFF. What’s worse is that depending on ping and distance, the hitbox goes to shit and the offset is not consistent, so there’s no way to use an alternate crosshair overlay effectively. This happens with combi, bow, pistol and caster.
Balance issues - From class stacking (multiple supports/dante combo) to flat out damage input/output stacking perks/specializations/passives, etc. Is just stupid and is mainly a Fireteam problem. While Pred can certainly stack damage, there’s no equivalent perk of “thick skin”. Even if you stack height advantage, impenetrable and iron side on a Zerker or Viking, you will still get melted in no time.
