Healer LB is really....underwhelming.

[Eisenhower]

It's an LB made to be used as a last ditch effort if things go to hell. All it needs to be.

That's what it IS, but it shouldn't have to be something so lacklustre and it definitely doesn't need to be relegated to such a singular role. That is why I think it's a shame the healer LB exist in the space it does (along with the tank LB).

For the melee and ranged DPS, their LB can be used to quickly damage targets that you don't want to deal with the normal way, to finish of a target before or after it's all gone to hell or just to push the fight into another phase. It's a tool that can be used in different situations.

The same cannot be said about the healer and tank LBs. Their utility is narrower and there are few situations in this game where they can be used to manipulate a fight in the same way the DPS LBs can.
