Now that I have been playing with trusts in FF11 it makes me sad to see how limited trusts are in FF14. There aren't really options for controlling trusts but they are responsive (as long as you attack the target), do more complex things like skill chains and magic bursts and they even use aoe skills, though most of the time for me they have been when I don't want them to use aoe skills.

I just wish trusts in FF14 had more of a purpose other than slowly single target down mobs in a dungeon and relieve the dungeon queue for DPS. Any level of customization of what they do would be really cool and I think they could continue to incentivize players to keep doing roulettes by just making the rewards more appealing.
