Bladeward was a point of contention back in the day, I never got the impression it was all that good at 80, Blood draining was my enchant of choice back then. the problem was that you just couldn't get it to stack quickly and the more mobs beating on you the quicker you ate your stacks. I wouldn't be wuprised if the weapon chain worked out to be better survivabilty due to the fight ending that much quicker.
