I haven't played SC2 very much, but got some time recently. While micro-ing hellions against Zerglings, I failed dismally. I have seen some pro-games were it's done very well. Now, there is a blatantly obvious lag between when I press 'hold position' hotkey and when the command is executed. Is the problem: - Keyboard: I have a few years old Genius KUL0210. - Internet: there was no usual notice of lag on screen. - I just suck, and good players have adjusted.
