I'm not as far along as the rest of you are but I'm not having too many problems with my guardian being locked down by normal mobs. Only level 18 but I can solo 2-3 mobs my level with proper CD usage and weapon swapping etc without a great deal of difficulty. For the record, right now my favorite weapons are 2H sword and a 1H sword/torch combo.
Yeah I died charging straight into a champion two levels above me this afternoon before help arrived, but I mostly wanted to see what would happen. Needless to say, it wasn't pretty XD
