I mained Terran in the beta on my way from copper to platinum 1v1 to my disappointment, since they have been consistently weaker than the other races (if your opponents knew how to play obviously, which means colossi/psi storms on one end and roach/hydra/infestor on the other), until I got tired of losing to 25 APM platinum players who just spam hatcheries and fungal growth. Now the only person I see who can sort of make Terran work is TLO, who can go for some sort of crazy triple-tech infantry+mech+air+the kitchen sink+your mom builds and manages to make them work due to his impeccable micro and harassment skills. I am not TLO. So I might try Zerg next time.
