When people say tvt, tvz, and micro manage what do they mean? Some guy was saying that a stimmed Marine is better than a Goliath vs a Mutalisk because the Marine and Mutalisk are both small units. Do things like size of units actually matter in battle? And a couple of questions about Terran. How do you defend yourself from another Terran player that has Sieged Siege Tanks and Marines / Goliaths protecting the tanks? I know of some tricks like using an air unit / building to further the range of tanks. Can you please tell me other good tricks / tech? Thankyou for you time.
