I think tank LB got to a decent spot now. Yes it still can be better, but defensive tools are, by nature, meant to be for preemptive use.

Aren't we using LB so we don't do fist mechanics in O11S? It is not a requirement where we wipe if we don't use it as that mechanic is definitely doable by staggering the firsts and lots of healing. Tank LB saves us the effort of handling the mechanic and the healing attached it to for a total net gain.

On Male and Female in O12S, we willfully ignore handing the same mechanic twice by "cheesing" them with tank LB. Again, not a requirement, just saves us the effort of doing the mechanic and the healing requirements attached to it.

I don't think LB is as binary as people make it sound here (where it is either required to survive 1 mechanic or wipe) because the only time this happens in this tier is O11S transition.

Can it still use improvement? Definitely, but is it as bad as we make it sound? I don't agree.
