No it's because just like Rowlet, it was the most appealing design of the three. You had a derpy grass hedgehog-like creature, a derpy water frog, and a cute/cuddly fire fox.
Tell me what you think appeals to the fanbase the most.
No, no and no. For every discussion about new gen, every time people start to ask what starter will you take, the majority is always : "Fire starter duuuh". There is a reason for that.
I also don't see the derpiness in Chespin and Froakie at all. And Rowlet is the starter with the least expression on its face, he's just there with a blank stare into oblivion (and he's gonna kill everyone mwahahahahaha) #TeamRowlet.
Also types I want :
Fire/Poison or Fire/Ground
