what must remain? for me:
terran:marines, siege tanks, goliaths, wraiths, ghosts, battlecruisers.
zerg:zergling, hydralisks, queen, broodlings(^.^), mutalisks, scourge(ESPECIALLY SCOURGE), guardians
toss: zealots, carriers/interceptors(pls blizzard pls dont take them out...)archons, dark templar maybe, arbiter maybe.
