Thanks for the feedback!
> The only viable strategy I've found is to survive long enough to buy War Trolls, and then drown the map in War Trolls
Yea regeneration is pretty powerful. I tried to make any unit with regeneration fairly expensive, maybe they need to be even more expensive :p
> Mana should recover between battles, but be more expensive the more you have.
Do you mean that if you buy 50 mana then if you spend 25 mana in the next battle that your mana should regenerate back up to 50? And that buying 50 more mana would cost more than the initial 50 mana? I guess thats reasonable.
> Shamans and Priests don't seem to provide their normal Healing skill benefit?
Ok I will consider having the healing effects of units heal units after a battle.
> Units should activate from the front of the formation to the back, to assist the AI in making more optimal moves.
Yea it is awkward when the back row moves first and gets stuck behind the front row.. I'll test what the original master of magic does, but probably doing front to back is feasible.
> There is no button to show all units, after clicking on All Affordable.
The 'All' button should do that. In case its unclear (its probably not since the UI is not great), the All button is separate from Affordable, where All should show every combat-capable unit in the game.
> I think being able to buy higher-level units, and heroes, would be cool.
You can buy all the most expensive fantastic creatures like sky drake and hydra. In fact, if you can get them I've found that most battles are pretty easily won. Heroes I am still considering how to work into the game, but I think they should be purchasable.
> Finally, If the player buys too many War Trolls, the game freezes.
Yea I can put an upper limit on how many units a single army can contain.
