I really enjoy the Squadron system as well. At a bare minimum I hope they at least bring them up to 70 so you can do some SB content with them too.
As it is now, you can level with Squadrons from 20-60, and then trusts from 71-80... but there's no NPC option for 61-70.


Additional stuff I'd like to see done with Squadrons beyond that:
- the amount dungeons that can be run with them expanded overall for ARR and HW.
- job promotion quests for trusts (instance trials undertaken with the recruit you want to promote)
- all jobs available as promotion options
- viera/hrothgar recruits
