I admit, I didn't want to like it. I kinda do, good job team!
However there's some problems I'm seeing early signs of: can we talk about vehicles. I already am convinced that I have to use one ability slot for a walker. Period, full stop. That sucks, the best matches are when nobody calls one down.
Can we disable vehicles for double cross? Or if you want to go the extra mile put one walker in the middle and let it be part of the strategy. Do you go for it? use it as bait? Drop a couple abilities on it so no one can have it?
In a 3v1 invasion I think the walkers are fun. But I can already tell it's going to be oppressive in 1v1.
