First of all, i have to say i'm really enjoying legendary heroes 
; i find it to be an overall improvement over fallen enchantress.
Here are some suggestions on how to improve the game even further:
- city spam has to be limited: the a.i. just fills every possible spot with cities; maybe force it to have less cities, but with bigger bonuses on production/growth/lower unrest, is a decent solution.
- there are currently no drawbacks for having mounted troops instead of walking ones; i would double the effect of swarm when used against cavalry or wargs mounted troops
- cleave is way too overpowered, maybe the attack should do less damage.
- wandering monsters shouldn't be able to destroy cities: just make them destroy buildings depending on their strenght; e.g. an army considered weak could destroy a building per turn, a medium one could destroy two of them and so on; when there are no buildings left, the city follows.
- allow the player to be able to refuse a champion when offered
- by razing an enemy improvement, players should receive resources, e.g. a shard shrine could give mana, a crystal crag crystals and so on.
Also, i found a couple of bugs:
- i had to escort two different noble women, so i kept one with my army and left the other one wandering trying to reach the estate on her own, she eventually died, killed by an army of monsters, but this ended the quest even for the other one.
- when a shrill uses static blast, the screen freezes for a second. Perhaps it depends on graphics settings.
Keep up the good work
