Why aren't people more players up in arms over the uselessness of Everlasting Flight? (For anyone that doesn't know: Demi-Phoenix applies a 20 potency/20 seconds AoE regen effect on the entire party upon being summoned.)

As a recurring summon in Final Fantasy, Phoenix usually revives/heals to full. That's not feasible for this game. So the developers best idea was a garbage regen? DELETE IT.
