TBH, I'm not sold on the idea of event cards, simply because its hard to balance whats already acknowledged as a very varied challenge. I'm worried that the event cards would make it all that more chaotic.
Also, even if the vast majority of players disagree with me, is it all that wise to implement so many new features in War #2, especially considering we aren't halfway done with War #1 yet? My only worry is that we are going to make the new system so unfamiliar that it will run clunkier and that if we feature lock soon (next War is in what, 4 months) we can iron out many wrinkles and perfect what we have.
