Someday I will get around to posting all the outfits I made for my male healer.
You can get some good unique-looking outfits by combining a "glamour gear" shirt with healer-specific pants/gloves/shoes (or some other mix of specific and generic gear).
I think this is a side-effect of trying to mimic the classic WHM gear with the hooded robe, while being restricted by the "piece by piece" nature of gear design in this game. Either they give you a hood you can never wear (eg. Lv50 gear) or it has to be detached from the coat so you equip it separately. Thus either the tight-necked 'nun' aplearance or the loose drape.
The fact they need to "switch off" visible hair for most hoods doesn't help with the nun look, either.
I think we need more circlets, personally....
New gear adds more designs and choices. You might not like most of those choices, but some you might, and so that adds new possible options each time.
You're not restricted to AF gear, or the latest variety of tome gear. Look at leveling gear, old endgame vendors, Centurio seals, Gold Saucer, PVP, GC hunt seals... look around. Try on combinations. There's a lot of potential and I don't think people realise how many sources there are for gear.
