There's lots of love for all 3. Oshawott got a LOT of hate back when he was revealed. Actually, I feel like these three starters were generally received much better than the gen V ones when they were first revealed.
I LOVE Chespin. Seriously, I've never warmed up to a first-form starter so quickly. Cute and cool, unique and interesting...I usually never care for the Grass type either.
I don't like Fennekin or Froakie, but just as a matter of taste; I don't consider them bad. So yeah, I personally would say they did a good job for Gen VI.
Anyway yes, I am so getting a Chespin plushie when they're released 0:) --- [LoL favourites: Janna, Syndra, Rumble, Fizz, Ezreal, Miss Fortune, Katarina, Volibear, Ahri, Lee Sin, Kog'Maw, Sejuani, Wukong, Nunu, Swain]
