I really wish they'd have redone what the Tank LB did.

It's all about the DPS LB's, because they actually progress the fight. A Tank LB will only add a retarded high layer of protection for an incredibly small duration of time. Only useful during situations where for some reason, everything is going wrong. But if things are going wrong, people are probably dying. Thus making Healer LB better.

Also you don't need LB3 for T13 anymore in undersized groups. It was nice while it lasted though.
