No offense, but that means you're playing against poor Defender players, as they have the exact same ability to choose the angle of their approach so as to not be as negatively impacted by obstacles...I just place asteroids in order to make it very hard for Defenders to k-turn and chose my angle of approach accordingly. The rest seems to all magically fall into place afterwards. I either win or give my opponent a very though match, even with experimental lists.
Yep if your defender opponents are reliant on the k turn then they just Arnt very good.
