Lets say I'm constantly sabotaging a gang leader by killing his thieves, building negative relation with him so I can get better relations with his enemies, eventually I would like this notable to disappear so a new one with normal relation can enter, but notables disappearing without you ever seeing them seems excessive to me
They don't really come back though do they? I liked exploiting the gang fights to level up my soldiers and level up my charm, but now when I defeat a gang leader he or she disappears and whatever backstreet/clearing/waterfront he or she was the owner of also disappears. It's a shame because you could smith, then when you deplete your smithing stamina you can start a gang fight and level some athletics (useful if you are a horse type player) and one handed and charm (gang fights increase relations with the gang leader's competition and with the owner of the city) and usually a few of your soldiers also gain a level.
As a bonus, since you wait during this process of gang fighting when the gang is gathering troops, you gain some smithing stamina and can smith after the gang fight and can rinse and repeat.
Also because there are 3 gang leaders who all own 1 gang location you always end up with positive relations with every gang leader if you take them out 1 by 1 in the same order. you always lose relations with the gang leader you attack at that moment but you gain relations twice from attacking the other 2 so it always ends up a net positive with everyone and these guys where the first to grant you the full recruitment in the city
It doesn't really work anymore now that 1 gang leader always disappears.
I really wish Taleworlds would stop removing the best exploits so fast all the time
