EX MGB should only be used in combos and in long range punishes.
What kind of situation would there be where having armor on EX MGB would help you?
Now, if you could EX your ducking to have super armor on it…
EX MGB with armor would be like Rog’s EX dashing upper, but about 10x faster and with the ability to launch them for crazy juggle damage. That would make Dudz straight broken. You could basically land it anytime someone throws a fireball from anywhere on the screen. You could also just plow through any sort of footsies. Damn… now I’m daydreaming about this.
As for having an EX ducking, I don’t really see the point in that. Why would you need armor on something that’s mainly used to pass through things? I mean, I guess it could help prevent you from getting poked out of it, but that doesn’t happen to me very often because I only use ducking to either juggle or pass through FB’s. Also, it’s already a focus breaker, so I think armor would just be unnecessary.
