They actually acknowledged the "it's too soon" argument as well, and I think it's a fair response:
On top of this, they mentioned that in a month or two they'd look at his numbers and have another discussion.
As for the moveset, I agree that Magic Burst is probably the move I have the biggest issue with over all of them. The amount of recovery options it covers are insane and while it does come with a big cost, Hero generates magic very quickly so it's not too much of a downside.
His neutral and side b are both insanely strong (I'd argue stronger than 90% of his menu spells) but at least they're consistent, and you know when they're coming out (stronger versions have a windup animation). That's also why I'm fine with Zoom, as the discovery that it gets more likely when you get within a certain distance of the bottom blast zone makes it so that you can be relatively sure they'll use it. If they do, you can rush to the middle of the stage and catch them with the anti-air.
Like I said, I don't agree that Hero should be banned, but I don't think their reasoning is awful. I also think they shouldn't be getting as much **** as they are considering A. They're a scene only in South Australia and B. This ban most likely won't affect the decision making of large T.O's all that much.
