i thought i would be more like 1550 or 1600 but i was also surprised to find out how many people suck ass
Macro definitely wins games. I pride myself on one of the most advanced strategical minds in the video game world, but I'm stuck around master level because my macro is garbage. Though I haven't played in a long time, I'm probably even lower now. One reason I never liked SC2, a video game you have to actually practice to remain good at.
Same applies to DotA. I can try to teach people game knowledge forever, but it will only get you so far. I can tell Hanna that one thing that will help her more than anything is just getting faster at moving her hands and her mind.
Is blink one of the best early game items you can use on SF? Yes. Can 99% of the community effectively use it? Nope. It doesn't matter how good you are with Lina if it takes you two seconds to react to a situation; you're already dead at that point.
Still, MMM is basically a first-order optimal strategy for half of the ladder leagues because people don't know what colossi/infestors/templar are or how to use them.
