Well hand-eye coordination is kind of important in Starcraft, it isn't really everything. I remember back when I was interested in that game that the advice most pros would give to noobs was to focus on macro. Even if your micro sucked you (i.e. you weren't very good at moving individual units around in battle) could still easily win a match by just out-producing your opponent (macro). Since macro is the slower/less APM-intensive aspect of the game, the importance of hand-eye coordination and reflex might be less than you think.Or at least that's what I understand of the lower-level play. At the highest levels, macro has been turned in to almost a science. Knowing the most efficient build orders and timings are a given. Handling economics isn't as important because everyone knows (and can easily enact) all of the near optimal strategies. That's usually when micro becomes a serious issue, and you start seeing players with a bajillion APM dominating the meta-game.
