The SC2 patch the world needs

Everyone is tired of the old meta. And I know how to fix that. We need under-used units to have more utility and purpose. We need players to have more ability to make plays and outplay their opponent. I think these changes would do a lot to freshen up the meta.

Thor: Given a "stomp" ability, which knocks back nearby enemies.

Brood Lord: Broodlings can now be microed and can use the burrow ability.

Disruptor: Purification novas can now combine to become 1 bigger nova.

Ultralisk: Can now use nanomuscular swell.

Hellbat: Can now use stimpack.

Colossus: Can walk across dead space.

Phoenix: Can now "lower" enemy air units, holding them in place and allowing them to be attacked by ground units.
