That's like saying you don't have a choice on when to enter Life of the Dragon on DRG, just because it's optimal to delay it for raid buffs.
There's a marked difference in "The dragoon delays it because of the party buff window" and "It's literally wrong to use Kaiten on anything but Iaijutsu and Ogi". When we speak of "Choice" in game design, it's not about whether the player is initiating an action, it's about whether there's a meaningful divergence of outcomes from those actions.

If your only outcome selections are Pass/Fail, it's not a choice, it's a formality.

Reapers have "The choice" of not alternating their powered up weapon skills.
Black mages have "The choice" of only using ice magic.
Healers have "The choice" of never using damage actions.

See how little that actually flies?
