Silver Protoss player, here. Whenever i play vs Terran i keep getting wrecked by 1 base bullsh*t and i'm pretty fed up with it. I'll get blink stalkers and voids off 2 bases and the Terran player will just start dropping all over the map and win off 1 base. I spread my units out as much as i can to see where he'll be dropping but by the time i get more units over to the spot to reinforce he'll have already just picked up his mass of free DPS marines and go somewhere else. Only the voids can keep up but he'll just fly over some hills/go somewhere away from my stalkers drop his death ball, smash my voids and move elsewhere once again.
Only way i win is if we both just start tearing up the others base, but i still lose quite often since he'll just lift his sh*t up and fly away. Terran is so gimmicky at these lower levels it's ridiculous. [more rage here]
