I decided to try DW/2H on my main, a Stamplar, but when using that combination of weapons, it causes constant visual glitching where my current weapon appears beneath my feet. only Reloadui fixes it, and I have to do it every few minutes, it's getting real annoying. I'd hate to have to abandon this weapon combo, becuase I'm liking the playstyle a lot.
Playing your character the way your character should play is all that matters. Play as well as you can but never betray the character. Doing so would make playing an mmoRPG pointless.
