Heroes.
If included they will not be able to level.
Only one of each Hero type will be aloud.
Item's will be usable. (for Heroes, and Units alike.)
Heroes would have ultimates.(they must be upgraded.)
They will be able to revive. (If its possable I'd like to limit how many times.)
Some Heroes will be better then others, and cost will reflect that.
nooooooooo
Not with them
