I hit 100 with my Barb last night :) Gotta say, that last lvl seemed like it took ages ... hit the mark sprinting away from a mob. I agree ... freedom to do as I plz now. Started a WD but don't know if I like that style ... I just really like to bash things Anyway, congrats & good luck!!
Might be just me, but first week or two after hitting 100 i really missed more paragon levels. I wouldn't mind extra 50. There was 1 less thing to achieve, less motivation to farm quickly. The feeling almost disapeared now, but not completely ^^
