Not since Achievements were released have I've experienced such frustration. I'm mainly referring to PvP achievements as they tend to effect everyone. People trying to do something completely irrelevant to the event happening. It's like having an achievement for "Mining/Herbing 50 nodes during a single battle for Wintergrasp." It's useless.
Does anyone remember when they were first released? Everyone was turtled in the flag room in WSG trying to get the "Kill X enemy flag carriers." and all the other achievements? They ruined the game. No one did anything productive.
QQ aside, anyone afraid this is going to happen again in Cata? Everyone going to spam the "Double-Rainbow" achievement and every other achievement associated with pvp?
