I'm still reading through the thread, but I haven't seen you respond to this, Rick, so I'll throw in my two cents. First, her classic skin's alternate form is not a cougar, not even remotely. Seeing as how Riot specifically called it "Aspect of the Cougar" I feel it should look like an earth cougar (save the saber-tooth tiger for a prehistoric skin*). Second, her French Maid and classic animal forms look very masculine. I played a game with FM and while recalling and facing the camera, I was struck by how old and wizened the browline looks. I mean, it's a neat look, but it fits a more grandfatherly character, not Nidalee. So, I'm saying I want sleeker cats and no Smilodons...yet.
Also, her pounce is weird on FM, it might not have enough frames or something, because it almost seems like an extremely short range teleport. She's just suddenly there.
*Y'know what had a "saber-tooth tiger" and was awesome? Mighty Morphin Power Rangers. Y'know what league could use as it's next five character skin theme? The Beatles & Yoko Ono...no, but seriously, POWER RANGERS. Make it happen. (After you hit level nine, the character dons their power suit) Black: Jayce Yellow: Nidalee Blue: Fizz Pink: Ashe Red: Garen. Green is Shyvana, and when she and Nid transform you get cool lightning effects 
PS: Where is my strikethrough text option? Do you know how hard it is to clearly convey humorous non-sequiter without strikethrough?
