I'm going Hrothgar and have too many gendered items to remember but ... ehh?

I mean, it would be nice. But I normally buy Mog glam for ... other reasons. Like for the hair on this set or the boots from this set. rarely do I get something for the main part and it just ends up collecting dust cause I hate clipping and like being able to color gear.

So personally I don't care that much. If it's important to you then keep the glam, save it for a day in the future when you think you Might play a male again. That's what I'm doing.
But don't think of it as "wasted money" if you go Viera and can't get a return on your investment into male glam.
