Probably seems random but I was really hoping to see an expansion of the glamour dresser functionality they added where sets could be grouped together to include the Alliance Raid gear. Dungeon gear can be grinded out solo for most older stuff and with duty support if it can't, but Alliance Raids need at an absolute minimum 3 people - more depending on the raid (LotA needs 12 minimum because of the Atomos, Orbonne I don't think can be cleared with 3 because of Agrias even if the previous two raids can be, and I've not seen a 3 man NieR raid yet, and definitely not Myths of the Realm or Jeuno).
So you would tend to hold onto AR gear over dungeon gear purely because it's harder to replace. Being able to group sets of 5 pieces into one glamour slot would be perfect. Especially with a whole bunch of new glam dropping this patch!
The comment about convenience trumping almost everything else reminded me of this old post (wasn't originally on The Urban Dictionary but they have it now under the definition of Linux).
