Do Tank/Healer LB1 and LB2 need an overhaul?

[Vandso]

Tank LB 1 and 2 are used at times. I will also use them in dungeons occasionally if no ranged pops it on a pull. Healer LB 1 and 2 I havent heard being used like ever.

Yeah like, Healer LB2 heals 60% HP of everyone after 2 seconds of cast time, like, why wouldn't I use an AoE heal instead? It's so bad and useless.
