Wow, more and more hiatus from me, and man, have I poked the hornets nest. Lets start with what I'm seeing right now.
About the logic behind the Greninja suspect, think about it like this: "What does it add to an already offensive metagame? What does it add when everything can hit harder (normal HO) and faster (weather in general)? Sure, its hard to counter, but it is also outclassed with shit like say, Kabutops (Shell Smash+Swift Swim makes it hard to counter), Omastar (same as Kabutops), Gorebyss (...), Mega Swampert (insane offenses and Swift Swim alongside solid bulk), Mega Jaws (stronger and faster), and Crawdaunt (Adaptability is insane) in rain offense, and on normal offense it is outclassed as a hard hitting water type by Mega Jaws, Crawdaunt (priority outweighs power here), and Barbaracle (to some extent due to Tough Claws and Shell Smash). Granted, nothing enjoys switching in, but nothing enjoys switching in on anything offensive in this metagame. It is still a threat, just an outclassed threat (technically speaking, though nothing outright outclasses its niche). That said, since the overall majority is anti-Greninja, I'm going to keep it
Banned. It's not that I agree with the reasoning, but the fact that nobody likes the idea of it being unbanned.
Now, with that shit done with, lets talk about shit in the metagame that may or may not stay.
Hoopa-U
I think I've made my irrational dislike of Hoopa-U self-evident, but just in case it wasn't, I seriously HATE Hoopa-U. There. Anyways, it gets nothing here, but nothing changes, except the environment. What do you guys think?
Charizard
It looks insane, no matter what form you're referring to. Even its normal form gets Solar Power, which means it can seriously hurt. Forget about a BD set. Then its already S-rank Zard-X comes along and tears shit apart, and Zard-Y, who can put up weather for ten turns, which means more Solarbeams will hit you. Thoughts?
Mega Altaria
Mega Altaria looks nasty, with that nasty Pixilate. It puts it in a worse league than Mega Pinsir, due to better bulk and Dragon Dance. Ouch.
Politoed
Drizzle. It brings Thunder, Hurricane and Surf. That means ouch. Politoed gets Drizzle. You understand?
Also, start thinking about mons that look broken so you can complain about them. ;)
