Alphastar did some inhuman stalker micro that the APM debate seeks to cover, but doesn't. Stalkers have a player operated ability to instantly move a short distance 'blink' once every 5 seconds. When in a fight, you optimally let the stalker(s) taking damage soak up as much damage as possible and then blink them backwards so they can recharge shields and continue firing from behind other stalkers. They don't stop firing, so all the work the opposing force did trying to kill a shooter, resulted in no outcome at all. That functionality is balanced by the fact it is hard for a human to time activating the abilities of many stalkers at once in time with the damage they are taking and perform the many other actions the game requires at the same time. Alphastar can perfectly blink back stalkers with limited apm because timing things is obviously not a problem for it, making stalkers way more value-for-money than they should be and can hold off high investment attacks more cost effectively. Ultimately sc2 is a game of economy and timing so this small change gives a massive advantage.
