What if we did get a Dragonite along the lines of the dragonair design and it became dragon/fairy? Dragonair looks as much a fairy type as a dragon type really.
I've always thought dragonite was fairy-ish, and was just thinking of suggesting this idea! Although I don't know about the dragonairish look. From the already shown alola forms, it seems like they tend to keep basic body shapes, and dragonite is as fairyish as dragonair. Besides, I would imagine that if an evolution gets an alola form, it's plausible that its pre-evolution will, so there could be both an alola dragonair and dragonite.
An alola dragonite would make me happy because I love dragonite, and if it could get typing that would keep it from x4 weaknesses it would give me an extra excuse to use it again.
Myself, I've always thought that it would've made more sense to change petilil and lilligant to part fairy than cottonee and whimsicott... I mean, lilligant seems just like some sort of forest sprite...This I can agree on. I never understood why Cottonee and Whimsicott got a new type while Petilil and Liligant didn't. Grass/Water would be perfect. Could have Sap Sipper and Water Absorb.
Anyone thinking of keeping alola and non-alola forms in a team side by side (via importing newly hatched ones from XYORAS)? It would be fun to keep one of each for vulpix and growlith lines (assuming the leaks of a water growlithe/arcanine are true).
Edit: also, can someone explain to me why a region based off of Hawaii has a number of pokemon adapt to be ice types? I'm all for ice/fairy ninetails, but I still find it a bit confusing...
