It's a great place to try out the new Monk.
Haven't gotten to Gorgons yet, but the Half-dragon seems to be about the same as he was in the alpha. The difference, of course, being that you have a lot more conversion points now than you did in the alpha; 200% knockback damage would be fairly brutal. Too bad most of the vicious bosses aren't set up very well for knockback, although I suspect he could splatter Namtar pretty easily (especially since magic attack will be incredibly helpful in that dungeon).
