suits me. i always hated heroes or superunits.
the mothership sounds more like an air to ground ship.
im kinda worried cause it seems the protoss are gonna have a huge disadvantage in air...the tempest shields dont work against air, the mothership cant attack air, the warp rays are not gonna be good against a swarm of mutas, and for the phoenix overcharge, all the ppl have to do is hit and run.
