I just got sc2, never played sc heavily. everytime i play, the people against me will win by bringing loads of biggest flying machines. how to counter that? what is the best unit to fight against air units. or what is the strategy to have strong defense.

I play in European servers, (not living in SEA).

any input is appreciated. (btw, should finish the campaign to be learn better? )

i did make air forces. but i was outted again.

how many svc are good?




will that help? mass production of marines is it best to do that?
