I love grouping. I can use all of my skills for one, and its a funner playstyle for me. Even in a duo my rogue becomes 10x funner to play.
Animations do not really bother me. For the most part they seem to fit the action and i agree with the Kaffis; idle time in combat is worse than a long animation. Yes, the animations are a bit slow on some of the more powerful attacks, but I just like to think of that as my rogue putting all their force into the blow.
