I dunno why yall are making such a big deal about this... and what yall are asking for seems like alot to implement. A switch? Between the original unglamour gear that you are originally are wearing and the 2nd switch for being able to see the glamour items? Yall is cray cray. SE ain't gonna do that.
What SE could do is set the glamour sets to our gear sets. This would be more logical than a switch. That way if you are a blm/smn or pally/war, you can have your glamour saved on your pally gear set then have a different glamour to your WARs gear set but the same exact armor.
I really dun have an issues with my glamours but then again... I haven't lvl'd my war or smn to 50 yet.
