... so bugs don't affect the ladder. Warriors are currently bugged, resto shamans got nerfed with lava burst and chim shot does 25% less dmg in pvp, ... can only imagine how many players have gained ratings/achievements they wouldn't be able to achieve under 'normal' circumstances. And then there are obviously the players who have lost rating due to this. And it's not the first time that it happens. Only solution I can think of is to freeze ratings the first week after a major patch so these bugs won't affect the ladder.
