A friend suggested.......
Someone I know that plays MCOC made the suggestion that Quake's aftershock/stun/concussion/evade shouldn't affect champions that float (Magneto, Rocket, Hyperion, Torch, Air-Walker). If you're not on the earth, how could an earthquake hurt you? What do you guys think of this suggestion? It would make an interesting balance and a lot more Quake counters.
(Feel free to disagree this post if this proposal doesn't sit well with you.)
