Is equipping multiples of the same Special too powerful?

[AFI]

I think we just need to nerf the hell out of George rather than limiting specials because, as someone's said before no other specials are really OP if you stack five of them. And yes there are ways around GDO, but that doesn't mean it doesn't require a nerf either, but nerfing all special moves because of George is a bit extreme IMO.
