Just FYI, some enthusiasts have 6 key rollover or even no key rollover keyboards that'll handle the controls for CC2 just fine. Also the game is dope in ways I don't understand. Keep killing it, guys.
For sure, I'm aware that some folks can handle it, but most can't.
By all means though, if anyone has an awesome keyboard that you want to play versus on, just let us know and we can try to make it happen! I just don't want to spend precious dev time on a feature that NOBODY can use. :)
