Clouds should roll for damage, but o nly do damage on hits. Or only damage on focus or something. That way they are less dangerous than asteroids, but more dangerous than Debris.
Rebels had an episode with gas clouds, and the clouds were like melting ships and stuff.

Or something weird like, "If you perform an attack at range 0 of a gas cloud, suffer one damage" to represent if the gas is easily ignited or something.
But I guess that concept contradicts their defensive buff . . .
