With the game having been out for some time now, what do you consider your favorite class so far?

I have played all but Merc to level 20. I have a 45 ice Monk that I settled on that I've slowly been playing here and there, but haven't made it past act 3 or 4 (can't even remember). It has been a couple weeks since I've played.

I am curious what people are favoring at the moment that have had more time to invest in the game. What has been your favorite build and does that equate to DPS fun or just fun overall?
