Skipping the major ones of more races, big class changes etc., here’s my wishlist of tiny things that wouldn’t upset the class balance or anything like that:
One single recolor of nelf cat form, that doesn’t somehow involve purple. Not a new form, just a color. I get that the “pink panther” theme must’ve caused minutes of Beavis and Buthhead sniggering at the original design meeting, but we’ve seen it now.
Being able to choose my ground travel form even in fly zones. Sometimes I don’t want to fly… Make it a choice among the mounts, if need be.
Change the mangle animation in bear form to something with a little “oomph” in it. What’s with that lazy, slobby backhand swipe? The claws are turning the wrong way, for crying out loud! Am I mangling that guy, or trying to wipe his nose?
Slightly less sparkly ground effect for efflorescense. Sometimes it’s difficult to see the loot-sparkle on the ground. Especially after a big pull and you need to loot quick because the DH tank is already jumping way ahead of the group. (DH’s do that, it’s in their nature to become overwhelmed by themselves and their awesome mobility. Don’t hate them, they have issues…)
