It bothers me to think that in the extremely, extremely rare event where a healer is required to use a T3 LB to raise the party, everyone comes up having Weakness. To me, in a situation where the whole raid is dead and needs to get up to continue the fight, having Weakness makes the raise almost (I emphasize the word "almost") useless. I've been told before that such a statement is pretty extreme because Weakness really isn't that much of a big deal, but in a fight like Titan HM or harder? I don't know...having Weakness would get you knocked out pretty damn fast.
