The Trust Characters take too long to do their attacks.

I just want to see their damage increased by a reasonable amount to compensate for them not attacking at all when dealing with mechanics. It's a lot more noticeable on fights with a lot of movement.

Perhaps some sort of item could be added in exchange for Grand Company seals or some such and when you use it in a Trust Dungeon it boosts their stats for that run?

Yeah or maybe their AoEs could be unlocked if you level them up. At least then leveling them up gives a bit of reward at the end.
