Well it seems that more people are comfortable with adding a new unit than I previously thought.
People have to understand that T3 air being so strong is one of the few counterbalances to extremely defensive and turtley strategies on large team maps. If you can’t effectively dominate air to make a path for your strats to strike (a SAM or 3 can’t stop a dozen strats from making a first pass) then you are indirectly buffing nukes, ecoing, and game enders.
So if we’re going to introduce a unit to counter ASF it should be expensive and only cost effective against ASF and not other air units. Maybe something like an aerial Fire Beetle that explodes and leaves a large but lower damage AOE cloud.
