True that. I vaguely recall one skill, shield expertise, in dd, but that only sets off on a 5% chance iirc. In bd, i played as an archer with the death knight as a warrior, so i can scarcely remember any shield skill in that game. In DKS, shields didn't matter much at all to my limited time playing it.
it'd be nice if there will be a weapon + shield in D:OS, if only to increase the survivability of melee chars. Don't know how well that can be implemented in a turn-based game, but we can all have wishes.
