While the idea that I can only get hit by two at a time in a blitz is slightly appealing, it also means almost no hope of winning up-declares against whale tiers. You need three coordinated offensives for some of those. Two isn't going to cut it at all for some of those.
Also the idea that YOLO attacks, or even infra shaving endeavors, could have have 18 wars at time? That's a hard pass.
Edit: But this would have been awesome way back in the day when I was interested in infra shaving to counter raiders.
