Gleeful glamour is the way to go imo because it gives you a consistent look based on your own appearance. It can be kind of a pain in the butt to get it right since if you go to the barber or transmogrifier it’ll show in the ui your base model but there are so many possibilities you can have fun with using the glamour item.
There’s little quirks to it:
-some of the heritage armors are only fit for the race they’re designed for (the earlier heritage armors are one size fits all iirc)
-druid forms for everything but travel form use the gleeful glamour, not the druid form
-some animations can look a little weird if the model your using isn’t rigged for it, I haven’t fully tested it yet.
but if you’re set on making something that isn’t in the game yet, gleeful glamor is the way to go.
