The bases seem slightly impractical to me, 2x4x1 bricks, it's actually how I can locate bases, whenever I look toward a base, my movement turns rigid, where as when I look at a clear area, I move as fluid as the game allows. That, and the bases seem slightly impractical as well. My team kept getting camped yesterday (Red team w/ Continous ;D), it took us like 10 minutes to clear out the blue team, another half an hour or so to gain some ground, then we kept switching control over the control point.
Nice landmines though. I didn't think they had a radius that big... whoops.
Overall, VERY nice, but maybe tone the brickcount down some, eh?
