I never understood this "gear won't work on unique models!" excuse

This isn't a problem for any other MMO where they actually get meaningful proportion options, so why is it that SE is the only company who can't handle it?

"Gear" can simply be automatically deformed and stretched over the character models' dimensions, with the only adjustment needed being a couple textures here and there clipped. It sounds to me like the players making up problems that don't exist to excuse the devs' laziness.
