Retarded balancing, retarded material grinding, retarded RNG grinding, missing core features like text chat in a multiplayer game, no flavor to the characters, locking characters to perks (they are changing this at least), atrocious netcode, paying more for less content, etc.
Another big one is leveling not requiring your perk's actual weapons and said weapons very barely being tied to said perk. So everyone just takes the best weapon (Vulcan) for every class.
