Let me preface this by saying this isn't a petition/rage post or anything, just to throw around ideas you may have for a non-limited version of BLU!

Here's my ideas! Open to criticism and building. Thought with BLU being a support caster in mind:

LB3: Limit Glove! ...or otherwise glamourable, based on abilities primals use after failed DPS checks.

Mighty Guard: Changed from a stance to a strong personal barrier/1-move mitigation on a long cooldown timer, for mitigating most moves you'd survive at full-health anyways, not instant death moves. Probably other exceptions as well.

White Wind: Changed from being a strong AOE burst heal to being a low potency aoe regen with raid utility (maybe similar to aoe AST arrow).

^^^^Alternatively, for WW and MG, a job gauge could be implemented which allows you to use either WW or MG as a strong AOE heal/mitigation. Maybe Off-guard could be a strong AOE damage buff/boss debuff as a third option. This would allow WW and MG to be fairly strong without needing to nerf them too badly.

Transfusion could be an instant cast raise, but still KO yourself. You'd need to use it very sparingly (maybe you're the last alive, with an LB3 available. You could clutch raise a healer for a healer LB3).

I'd love to hear other ideas!
