Adventurer Squadrons are missed opportunity
Just imagine that instead of generic bland 'missions' we could send them in real dungeons of appropriate level and they could bring back it's loot for alts or glamour. And at lv.50/60 we could send them to at least ARR primals/raids, or to HW primals with less success rate so they could bring their glamour once per day.
In this case they at least could be remotely useful, but right now they are worse than retainers who could bring various items from ventures (including random dungeon drops) with much less effort.
