if anything it should be made into an aoe application with a different animation. it's probably never worth it to use even on double target aoe, but maybe if it was a full blown conal aoe it would be worth it to use. then they would kinda have reason to add the aoe yukikaze they showed in endwalker job actions preview.

aoe rotation without most cooldowns and ogcd could be: meikyo > mangetsu > oka > tenka goken > tsubame > yukikaze aoe > higanbana > tsubame higanbana

Then we can get back a conal aoe. It fits better on an aoe dot than it does on tenka goken anyway. Meaningful positioning requirements for the dot application, then pumping damage in the fray with tenka goken.
