I guess what I was trying to say, in general, was that since SC2 required less micromanagement of your macro (auto-harvesting, etc), players had more free time to spend on unit tactics.
In GSL season 2, MarineKing showed that stimmed marines could counter banelings. Then the rest of the playerbase quickly adapted his tactics.
At MLG Anaheim (2013), the SlayerS terrans (ie multiple members of the SlayerS team) placed 2nd, 3rd, and 4th and destroyed all zergs with their blue flame hellion play.
Those are just two examples of the sorts of tactics that once discovered are quickly assimilated into the metagame and quickly go from innovative to standard play. So my hope was that AI could speed up the pace of tactical innovation.
