I have done some basic mogging this expansion only because I find the gear that drops for Horde to be particularly hideous.
That said I don’t generally transmog my characters. I understand that it is a very popular thing among the player base but for me it’s just not something I care about for the most part. I don’t get why that’s so hard for people to understand.
I don’t care what other characters look like. I can honestly say I’ve never even thought about it while playing. I also don’t care if other players look down on my characters because they aren’t transmogged.
