Evasion, health, damage bonus need to be raised to the vanilla level, I want to played it with your rebalance heroes mod but with no Evasion, Heroes never dodge strike

I'll test a little bit further to see how they perform on duels exactly, thing is, with the added bonuses, characters perform overly well in both campaign and battle, theirs retinues do better, the army does better etc, so dropping their combat capabilities seems like the smart choice.

As for health/evasion, they're nerfed on levels (85-150) of their respective stats, to avoid health bloating on champions and to avoid unkillable sentinels. The mod page doesnt mention it, but if you reach lvl 200 on any stats, they'll get a huge boost to compensate sacrificing their other stats (As its fairly complicated to reach lvl 200 in any stat).

I'll post again when i test a little further about what you mentioned

Ai suffers from having commanding general with low resolve. -3% replenishment is massive nerf
