i didn't do any pvp in last bwe, as my current pc is just too crappy for that, so i can only talk about questing/world bosses and theoretical pvp.
and i agree, i was actually planning to go with a sword+dagger & shortbow shadowdancer ("shadowdancer" sounds just so much cooler than "with stealth and mobility and stuff" xD) build for pvp, but sword got nerfed (the current builds still don't reflect those changes) and i was surprised how much i liked dagger.
i guess i'll still go with sword+dagger for pvp though, that would ofc take away from the burst szenario. although Flanking Strike should hopefully do quite a bit of damage too.
