The fact remains; heroes shouldn't have huge effects on the games. Just like casters. Casters shouldn't have huge, overwhelming effects on the game. Nothing should. Perhaps a combination of units should, but no individual unit should overwhelm the game to the realm of imbalance. Anyone who knows a thing about game balance knows this. Heroes do that. One unit is, in every aspect, more powerful than even 5 supply worth of regular units (Which they take up). Prove to me, now, that heroes are not more powerful than 5 supply worth of regular units, and in theory "Balanced" units. Gogogo.
