What you're asking for isn't a discussion, because I've already posted a topic of discussion and it has gone ignored. If you don't agree with my definition of what an extreme should be, discuss that. It shouldn't be about the example I provided in the form of Ike. You're asking what I think is wrong with Ike, not why I don't consider Ike an extreme. There is nothing wrong with Ike because I'm not the developer and I can't tell you if he's working as intended or not.
In regards to Ike specifically, he has slow attacks, range and disjoints, strong movement, and powerful hits. Which of these is not like the other? I'm not saying he's too strong. I'm not saying he's too weak. I'm saying he has tools that the archetype shouldn't.
But this is Tier Speculation, not Balance Discussion. None of this matters.
I think Mewtwo is still really really good.
