the biggest thing i think about meching is you want to move when you have maxed out, but harassing with hellions is fine. again the biggest thing i think is that you want to keep your gas save and don't lose your gas units. losing minerals is at the most part fine as long as he is losing minerals too. there is a you tube video on Apollos channel that really helped for me about mech timings and builds which got me into diamond. just sit back with thors and tanks while you continue to attack with hellions! that is my 2 cents hopefully i helped! for give me for the if any type O's im trying to type fast so my teacher dose not find out. -got to love high school-
