Here's what I would like to see do:

Need:
1. add a checkbox in duty finder settings that consents to allowing yourself to Queue with a BLU mage, making it so no one is forced to deal with one if they don't want to. (also make it so this box is only selectable for duties that have already been completed)

2. Let BLU queue for duties that have already been completed by the player.

QoL:
3. Add EXP boost to mobs that are part of FATES, the reward for completing FATES is about the same as killing 1 mob anyway, so really this would just make it more interesting than just killing regular overworld mobs, it would also help make fates become more active.

4. Make more spells instant/oGCD so the rotation feels better.

5. Increase Learn rate to 100% when clearing content using the min ilvl feature.
