Well, currently the top gear is the Job specific gear (unless you're looking at Alex savage gear), so currently this is less of an issue. But just like with AF i45/50 and AF i90, we'll soon go back to the top gear being shared for tanks, healers, casters and ranged physical. (Melee DPS, on the other hand, still get separate gear sets... *grumbles* MNK/DRG share Str-base, and NIN is Dex-base... but MNK/NIN share def/mdef whereas DRG has higher def. So yay, they get to be speshal snowflakes when it comes to gear.)

This has been an issue for me even before HW, especially since I had all tanks, healers and casters at level 50. Sure, I very rarely used half of them, but I still liked the gearing up and glamouring bits of it ^^; I'd even have to resort to carrying separate gear pieces at times (keeping one of them slightly lower ilvl, usually) just to be able to use a "job appropriate" glamour.

TL;DR version: Yes please ;_; I'd like to be able to have job-specific glamours without having to use separate gearsets when the "top" gearset is shared.
