Prayer Wheel and/or Gray Waves: OP?

Discuss.

Prayer Wheel is good and bad... it requires a minimum of one other skill activating to have any effect, and the effect is only as powerful ("only") as that one effect x 4 (or x2 if your way of buffing is through Hone or Fortify Fliers), which often means that teams and positioning or other units' actions will have to be specially composed to get the skill's full effect, but it can also maximize all stats in a rather fail-safe way: you can put an Even/Odd Stat Wave on all members of your team (preferably each member getting a different stat but on the same turn), then, on Even/Odd turns, you can make L!Azura give any one unit an All+6 boost.

I think L!Lucina's Future Vision skill is worse than L!Azura's Gray Waves, that skill grants free forward movement and actions for multiple teammates and is exploitable via the Link skills. And previously all fliers could (but obviously not in the same exploitable way) grant infantry and other fliers 3 movement anyway.

It would be excellent if they gave all refreshers PRF assist skills. They could put Olivia on a new power banner with perhaps a new PRF weapon and a PRF assist.

Incidentally, I conceived of Larum because of a guy who made/namedropped her in a dancer's PRF weapon thread. His variant was as a tome unit, but I think a no-maj unit makes more sense:

(An ally with Sing or Dance cannot perform another action.) Unit cannot be granted an additional action through assist skills. (SP 400. Skill cannot be inherited.)
