I never said a single thing about Ash-Greninja in my life, so I don't know what are you talkin about.
Maybe it's hard to understand for some of you, but the point is to have a healthy and funny meta who attracts new users and not scary them.
Right now, in my opinion, the biggest problem in this game is stall, a stall predominant meta never gonna be good for the business, and its as simple as looking at the ladder every month and seeing how half the users on that list completely suck but make it just by abusing stall teams while playing 40 min battles, and here I am being OK in banning a stallbreaker, why? because first and foremost I want a healthy meta who gives variety of strategies without forcing you to using some mons just because 99% of the server is using the same broken mon.
Anyways, the guy above me explained it perfectly with a smart approach instead of posting some stupid [heck] like you did.
