Mostly Yay face here!
Pandas are rather cute and a bit silly, but so are bipedal cows and sexy goats, bring on the silliness I say! Whether or not I roll one depends on the female model, and it being more cuddlesome than a female dwarf...
I just love having a toon that looks weak or homely but that can kick ass, doesn't everyone who plays a gnome feel this way?
I'm really looking forward to the pet battle system, I love stuff I can go off and do on my own when I cant sleep at 4am. While the comparison to pokemon is valid, I never played that. I backed the wrong horse way back when and played Azure Dreams a lot instead! :p
I also quite like the idea of the challenge runs, where gear is normalized, hopefully this will mean I can continue to have fun on my random alts without the pain of regrinding for reps/gear that generally puts me off and causes me to bench them.
The new areas look lovely, like saerdon I loved the asian and arab themed stuffs in guildwars, its just nice to see different styles and cultures being reimagined. Saying that I hope there is a darker feeling zone, as I tend to end up liking the netherstorms/deepholms the most.
The new talent system is an odd one, if they want to try and get away from Cookie Cutter builds surely you would accomplish that with more choices not less. I had a quick look at some of the trees and there is still a very obvious pvp/pve skill divide. I guess for me it will be like the change to Focus, where I continue to play despite it rather than actually preferring it.
Warning QQ inc!
If blizz are so intent on all things fun, give back Eyes of the Beast dammit!
