Hmm...there's no single enemy in that dungeon. It's completly empty, is that normal?
I tried battlefield dungeon 3 and it works without problems: there are enough enemies.
But I want to boost up my stats first in level 2 and then in level 3.
I took a fast looking into Act 2 and I really need expierence points from the battlefields <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
