That new zerg unit. I bet it's a roach morph built for anti air early game so zerg don't get fucked when expanding from banshee/VR. Ofc HotS will probably be a whole new ball game, but the principle still remains.
I really do feel it's a roach morph for sure. Plz no seige, we don't need more terran crap to win games i.e. infestor IT baserapes.
