If you've been following the Alt Appreciation series you'll know that I love alts I have multiples of the same class three Druids, four Paladins etc but I have only one Rogue and I'll only ever have one Rogue. Not because she's special to me, not because she's important to me but because I loathe the class!
When it comes down to my love of classes I take a few things into account. Can they tank? Can they heal? Can they DPS from range? Most classes cover at least one, sometimes two of these. Rogues cover none. I hate playing Retribution but that's Ok because Paladins can both tank and heal.
I created my Rogue during Wrath to help my Priest get her Insane title by farming lock boxes for Ravenholdt reputation. Afterwards I spent a little bit of time with a friend and got her to level 83 where she'll remain until I inevitably delete her. I just detest melee DPS and that's all a Rogue can do. Boo hiss!
