It's humbling but also necessary sometimes to admit when you're wrong, and hoo boy, was I wrong about transmog. I used to argue that transmog would diminish the value of new art - instead, I often pick up pieces of gear in current raiding as much for their aesthetic appeal as anything else (I have the complete Warrior Tier 16, a set I don't even like
, just because I want to be able to use the pieces for mix and match mogging) - indeed, my tendency to use our raid breaks in order to mog my gear often means I mog pieces I'm wearing to look like pieces I just got.
Similarly, I used to argue that with transmog, people would just mog to old tier sets (indeed, even Ghostcrawler mentioned on the WoW Insider show that's how the feature was originally conceived) but now I find myself mogging based on a common theme or color scheme or just on a whim. I have mogs that are based around a single piece of gear, or a color scheme, or just because I wanted to look as awful as possible
I find that being free to customize my own look has me more invested in my play - there are days when I really feel like just putting on the Heroism pieces and using an old Blackrock Spire 2h weapon, and days when I'll tank a few dungeons just so I can put on a completely, wildly mismatched set of pieces that make my Icecrown Glacial Wall look absolutely ridiculous. I like that people don't know I'm overgearing the content just by looking at me anymore.
But most of all, I love being able to use
my enormous weapon collection. Before transmog, I collected weapons just to have them - By the end of Wrath of the Lich King
I had a large collection that was just gathering dust. I don't know and didn't then have every weapon I'd want, although I've gotten pretty close to every 2h weapon I would collect (I didn't really like any weapon in Throne of Thunder besides Uroe, for example, but I like most Siege weapons) - but there's just something so much fun about imagining my character going into this enormous weapon rack and just yanking out Ashkandi for the night, or deciding that it's more of an Armageddon raid.
I find, for me at least, having this kind of control over my character (especially since it's control that in no way changes game balance or affects play directly) incredibly satisfying. If I want to rub Garrosh Hellscream's face in the fact that I can dual wield Gorehowl, I do. It makes killing him even more fun.
