One of the main reasons DotA succeeded (please do not flame answering Demigod is not DotA) is because of the "tidy" gameplay.
A Nash Equilibrium is a state where in a competitive game between two players using the same tactic (let's say, tactic A) do not benefit themselves or the other player by switching to any other tactic, besides tactic A.
This is -unwillingly or not- achieved in multiple aspects in DotA. (It does not only apply to the early game farming -tactic A, vs kill, tactic B, where early game you will harass your opponent have him go to base while their creep kill you-, but also creep pushing early and mid game.)
To my opinion, and forgive my ignorance if this has already been stated, quoted, or answered by the devs, if the Generals have direct impact over their creeps' movement, this could be vastly hurt equilibria in Demigod, thus resulting to a less "tidy" gameplay.
What do you think?
