FAF absolutely benefits from action spam, to the point where it breaks the game balance.

T1 assault bots lose to T1 tanks, and they are supposed to because they are half the price and much quicker to build. You can dance them around if you click enough and they will dodge the tank shells… a few micro’d bots can then defeat 10s of tanks. That swing in mass efficiency is already enough to decide the game on maps smaller than 20km.

RTS will always benefit from intensive micro because time is another resource. Doing more actions, assuming they are of positivity utility, gives an advantage over an opponent who does not.
