they are doing protoss first, then terran, then zerg. dont worry, kerrigan's time will come.
the warp ray looks like a neat unit, but i wonder what would happen if you moved the unit getting attacked by the warp ray away? would the laser just stick with the unit or would the warp ray have to deactivate, move, and start all over again? if the second one is the case then the warp ray is gonna be fodder for good and even average players...
