Battlefist on a warforged monk would be completely and utterly devestating to any other race trying to be a monk. Adding 1.5 times the damage would hurt, bad.
Wand Sheathes? You mean I get to treat it like a clickie instead of dropping my weapon and drawing the wand? Sign me up.
Armblades and Arm bows? A little less useful in DDO. Or potentially game breaking.
There's all kinds of things that could be included specifically.
Honestly, I'd rather see bigger and better docents.
