Could we have a cosmetic change to reflect max sets of various tier pieces? Like how the Wailing Caverns set made your cat form a snake, we could have things like being a frog if you have 9/9 T3 pieces.
The content team will definitely be looking into this.
The team loves these types of additions turtle has made.
Our main focus however is on getting all the Turtle content we lost first.
But expect great things in the future
I main resto druid and I love my tree form but it would be cool to add a glyph or quest line to keep my caster cosmetic or at least add my weapon like moonkin form.
