I find that I keep getting destroyed to a tank/marine drop in my mineral line. This generally happens early game before I'm two base saturated and have roach ling bane. (for the obvious MMM deathball from a scout.).
When you do a scout for terranTerran initially (10 supply), you can't tell this is going to happen to my knowldege. When I sacrifice an overlord at say 6:30, you still just see a factoryFactory and a starportStarport. This is still indicative to a mmmMMM push.
My question is, do I just blow all my money on static defense and leave my entire army ready to deal with it or is there a better way?
this is for hots by the way
