Niantic doesn't even give a damn about stats or even pokemon who has advantages from it's speed.
Abilities is a good way to utilize pokemon to it's fullest potential, and even create a better meta or for worse.
But in the end, niantic have to deal with its giant flaw first which is how to make other players who lives in rural places to stop using pokevision and stop banning people who use local coffee shops wifi. I mean WTF my friend got banned for using a WIFI? i mean what the hell is going on? Casual players getting banned while gps spoofers who casually taking gyms and prestige to lvl 10 overnight doesn't get banned?
In conclusion, niantic need to fix their game 1st before implementing anything else in the game. But that's just my opinion.
