Cover now takes into account your defense, not the target's.

Rampart and Sentinel now work with Cover. I forgot to check, but I'm assuming (based on casual observation) that Shield Oath works as well.

Cover damage still bypasses Hallowed Ground.

Also, was the range always 10 yalms? It feels longer than it was - could be my imagination. Anyway, Cover is pretty okay now. I'd like the cooldown to be shorter, but at least it doesn't give you the defense of a white mage now.
