There will be bosses.
And I wouldn't mind a creature portal, like in the fourth game. Or a super-unit for each castle. It could be hired once a month or once per game, but only after building the Tear of Ashera.
Doesn't this just remind you of the good old WoG?)))
No, I'm afraid they won't balance it. "Heroes" already has a shaky balance, and something like that... mmm. No, no, no, no. Unless it's just for a single scenario - such creatures would be perfect for the most unpleasant battles)
A creature portal is interesting...
The main thing is that they don't cancel caravans - they are so convenient.
P.S. Damn, I need to re-check the fourth game. It seems there were more interesting ideas there than I can remember.
