We've discussed this dozens of times.
Oh, wait, you're just too apathetic to go and look it up, tormenting the rest of us with the same old thing.
Heroes are OK in single player, but they will just be stronger than normal units. And you had better keep them alive, or it's pointless. I'd rather have one long, epic game than a short game with multiple storylines.
Heroes had better not be in multiplayer. When they were used in WarCrap III, they only took away from the gameplay. It was no longer 'who could control his armies the best'. It was "who could level up his heroes the fastest". No tactics, no management, only unrealistic heroes that could eat entire armies for breakfast.
ES has made a few good RTSs. They know better than to muddy up the game with Heroes.
Lethe:
Then you should be pretty happy with the game; it's a lot of fun.
Even if a squad of marines out of dozens of units on a battle field has shoulder pads .25" too thick for a fanboy's tastes :)
Inspires confidence, no?
