All the hardass clanners are plaguing AC:R at all times of the day, lately... Bigots who camp on roof tops or abuse boost cooldowns to stun lock are the bane of all multiplayer experiences, in that they completely destroy the spirit of the game just for the sake of winning a fraction easier.
Luckily, rarely are these clan bastards in the same lobby to successfully abuse such tactics. And even when they are, it ain't very hard to just leave into another lobby. Gaming in the middle of the day sure has it's pluses. All the more motivation to work night-shift jobs.
