1. almost half of my generels killed by enemy's assasins,even I have put 3 spies of mine in the city
2. The knights ,even the generel kngiht is too weak ,is very very very easy to be killed by the long range weapon , I mean kill by the cavalry or horse archers,even the very cheapest horse archers .
3. very ridiculous:my spy ,75% 88% even 95% chance to spy enemy'city or castle,failed more and more times ,dead.
but AI 's assasin etc ,even 5% chance ,they can kill my general ,even the prince
