These mostly seem to have been solved in modern SC2 already -- swarm hosts are no longer a lategame unit, high templars and ghosts are extremely vulnerable to units like speed banelings, viper abducts are powerful against motherships, it's fairly rare for tournament SC2 games to last more than 20 minutes and when they do it's not because there are fields of static defense splitting the entire map: more like mining out for a 200 supply fight, after which the next fast remax's composition choice will decide the game.
