No kidding major /spit on the collection quests.. worst part is i just barely finished Hellfire so I know tons more are to come =l.
I feel ya.. at first it doesnt seem that bad once u hit northrend but it becomes a pain if u start skippin the collections.. I did at first then from 74+ i took most of them.

As for questing over boosting. At the min im so down on quests to do that arent a real nightmire (low drop rate collections) I think boosting would be quicker. He ended up going to arena so way nay good anyways.

Bout 5 bars to go
