The same set that makes you a quadruple amputee with mechanical limbs. And is also only one set out of a sea of other sets.
Healer gear has a massive issue with lack of variety, to an almost ridiculous point. The grand majority of the sets are WHM-themed or have frilly bits tacked on for no reason whatsoever... or are just outright ugly like the stupid maternity robe from E1-4 or the Cryptlurker healer set being a trash outfit based off the ugliest sorcery robe in the souls series.
Honestly just wish they'd remove restrictions so I could use more of the adventurer-esque sets that scouting and ranged get on healer. And I'd take that any day over doubling the glam dresser slots and I'd even take it over a proper glamour log.
