Heroes 6 - Discussion

I recently downloaded the game Eador, it's quite interesting, the graphics are not great, but the game itself is good. You can borrow some ideas from it for Heroes 6. For example, the army composition: 5th-level creatures: you can build 4 1st-level creatures, 3 2nd-level, 3 3rd-level, and 2 4th-level. And the hero can take 5 1st-level creatures, 4 2nd-level, and so on.
In Heroes, they could do the same, so that the Boss can take several 1st-level creatures, several 2nd-level, and so on. So that you can't replace a higher-level creature with a lower-level one, and so that there are creatures left for the 2nd hero or for defending the castle. Otherwise, when one hero is too powerful, it doesn't feel right.
