personally im havin fun in UF. been in it ALOT have the group progression done (which was fun), the first 3 raids were a Trip, Im not max aa (just under 3k) and still quite a bit to buy and ive been flyin thru aa's pretty decent rate, was fun to solo Volska and make a monk cry. Revenge from PoFear is so sweet
Still augs to get farmed out, aa's to farm, and LOTS of achievements i wanna finish. Yes the Achievements gives you a whole new personal goal to work on. even if u dont step foot into UF, theres class specific achievements u can work on, etc. So yeah, i recommend UF despite whatever class u wanna be.
