I like almost everything, except for the "Portal to Town" spell. It should be made like in "Heroes 3" (so you can teleport to any town of your choice) or "Summon Reinforcements" should be possible from any town.
I would slightly adjust the bonuses from the "Recruitment" skill... What is this +3 peasant, +2 archer, and +1 pikeman... it's not even funny... Something like +13, +12, and +11 would be more noticeable, or if you leave it as it is (i.e., +3, etc.), then change it in another way, i.e., +1 Angel, +2 Cavalier, etc.)
No, seriously, the bonus isn't great, but almost doubling the increase is too much. Maybe then make diplomacy with a 90% chance of joining? Or treasury management for 2000-3000 gold? And to completely ruin the balance, increase the speed aura from 1 to 3. Yeah, that's too much. But I also think that 3 peasants, 2 archers, and one swordsman is too little. You could, for example, make it always work, and not just when the hero is in the town. However, this is only good for some factions, but not for the Dark Elves....
And also, get rid of the stupid training restrictions, thanks to which all the advantages of playing as a Knight were ruined.
So back off your rules,
Back off your jive!
Cause I'm sick of not living,
To stay alive,
Leave me alone!
I'm not asking a lot -
I just don't want to be controlled,
That's all I want.
