I hate questing with other people, if there is one other person killing the same type of mob I am I throw my cat out the window out of sheer rage.
So because I don't want to go to all out war with the RSPCA again like I did when Wrath launched I've decided to level by tanking the random dungeon finder. But looking at Totalbiscuit's marvelous videos I've become slightly reluctant to do this.
Now I ask you to provide me with reasons why I should or shouldn't quest to 85 so I and help me those in a similar predicament make up our minds.
