If there will be 200+ people it can always come back to 3 sides.... but for now it should be 2.
Agreed.
The war will be a lot more dynamic, too, which is in and of itself fun.
I do miss the fullscreen map we had in WBs though. You got a much better idea of what was going on than you do when forced to "fold" your map onto a clipboard-sized area. A fullscreen map option would be a good move. Most games have this (even Zombie hunting games have it).
The clipboard is a nice work of coding prowess, but I think it probably confounds noobs a bit.
