well, pulling dosent matter what proffesion you are, just switch to a bow on your warrior real quickly, and shoot 1 guy from the mob.
try looking up meta builds for your heros ( jin and gwen sound good if you put interupts on both, alothough ussally i use Sabway and put secondary interupts on the MM and the SS. Search for Sabway on
www.pvxwiki.com, as it is the bomb)
that dungeon is a real doozy, no joke. In normal mode it is no problem for more experianced players, but newer players should probably start off with easyier dungeons like the ooze pit, or Arachnis Huant.
