Also, there seems to be little difference between just saving the AP and delaying, but IMO...I dunno, it feels better? Haha. Battles tend to start with enemies all over, but letting them go first, they often run towards my group and naturally clump. My Jahan has Glass Cannon, and if he just saved his AP, it'd be over his max (since recovery is doubled, but not starting).
If you want X to buff Y and X goes before Y then problem solved. If you want X to buff Y and Y goes before X then Y saves AP and X buffs immediately, giving Y extra AP on their turn with the buffs.
No one said you had to skip both of them.
