There are some balancing suggestions.
1. Need fortifications for towers.(Barrier or something)
2. Move the mines into the fortification.
3. Trees should be closer to the castle.
4. Reinforce the fortification to not let enemy horses go through it.
5. Reduce the amount of money when captured the flags.(Serfs are poorer than Soldiers)
6. Weaken the default weapon.(Serf is useless because default spear is enough for fighting)
remove default bow from archers, replace spear with spiked club, Only Infantry get default shield, etc..
I cant wait for new version. Thank you Laszlo!
