I just wanted to share this with all my lock friends.
If a rogue or a war, or any class that can reduce your armor does so before you cast demon form.... you will gain the % of the current armor you have. It turns out to be less then what you have normally.
Sorry if you knew this, but I just wanted to express to everyone how our only anti-melee ability can be exploited with ease.
If anyone really thinks locks are ok, they need to go jump off a building for being so stupid and ignorant.
I haven't tried it yet, but I would logically think this would work against druids going into bear form. I have no idea though.
