My response was the title of this Breakfast Topic, ultimately. I like transmogrification because to me, it's fun. It's fun going out and getting just that perfect model for the look I'm trying to create, whether that's to match up a set, or to deliberately clash with a set. I like putting together theme outfits I'll probably only use once (like the above set in muted blue/white/grey above) to match colors or just because it strikes my fancy. But most of all, I like transmogrification for the exact reason my friend hates it - it adds nothing to character power. It doesn't add numbers or make you a better player, it just allows you to choose your own look. I don't think it's constrained the design team in any way - it just means their work will be on display longer.
And that I need a lot more bag space, of course. That doesn't really need to be said.
So now I ask you - what do you completely love despite other people's disdain for it, or hate even though everyone else seems to love it?
