Yeah dimension door is good, but is takes a standard action (if only this class feature made an exception and made it a move action!!!). I really sucks using up that turn (especially if the battle could be over by then), but putting you self in a postion to get AOO's is always a worthwhile move...But you still don't want to wait for Horizon Walker's dimension door (acquired at level 11, iirc), correct?

I suppose I could always ask if the lycanthrope template is an option? Although, I've fully understood how the HD and a few other things with it worked.
