nah u need to put 1 oathsworn and 1 nemesis for your "main" general so that he get both buffs

It means rivalry between other factions and rivalry doesnt have melee evasion. You mistook it for oathsworn bonus

The game actually says in the advice that rivalries can push people to be better and the patch notes specifically nerfed the melee evasion from rivalries. Seems intentional.

Does this mod still give the rivalry bonuses if the rival is in the enemy army?

I like that you provide reasonings behind your mods and why they make sense. Thank you for these.

im pretty sure they do that to provide choice, do you want generals competing with eahc other? (rivalry and hungry generals are more effective) or do you want happy more content (less hungry/effective) generals. TW incorporates RP into their strategy really well. mechanics like this are usually designed with that in mind

I did not even realize the "Nemesis" bonuses in the game until now. If what you described is true, then it should be fixed by CA too. I have been using a mod to remove negative relationships completely (generals will not hate each other anymore), is that better or not?
