I wouldn't mind it as a option. You could even reduce the XP to keep it from being exploited also make the mobs +4 or higher to make up for loss of powers.
You should come out of Dwarf and activate Eclipse prior to it ending. I play Tri-Form so rarely do I stay in Dwarf other than the Mires and Mez-Snap out. Eclipse carries over into the forms now so it really removed the largest benefit of Dwarf the added RES.
