A single Strat Bomber with air coverage can ruin the ecconomy of an entire team and decide the outcome of the game all by itself. Basically when you see a Strat running amok at the 20th minute mark eating up one mex after another both teams might as well agree to quit right there.
The problem boils down to ASFs being the only cost-effective counter at the detriment of Land and Navy players. Neither T3 Land AA or T2 Cruisers can prevent a Strat from infilitrating the backline and SAM sites can easily be avoided on large enough maps.
I'd like to see T3 Land AA or SAM sites be reworked to effectively combat Strats across the map. Maybe double or tripple their range but make it so they fire only once every 30 seconds while only being able to target Bombers? Whatever the details are i think a drastic increase in range is necessary.
