I loved playing Classic WoW and I can't wait to take another bite out of that sweet sweet vanilla pie but that doesn't mean I'm done with current WoW. Here's the thing, you can still like and play both! I know huge shocker, right?
Transmog allows people to express themselves & show their favorite armor at any point of any day. In Classic you don't have that & most people ARE wearing the same armor & look mostly the same. That's what I like about the current WoW.
