I know this has been an ongoing issue with the game so far and that there have been several different patches and updates meant to help address this so I wanted to share something that I did to my own game that has seemed to work rather well. So far I only got to about 900 days in game so take it with a grain of salt as this may not be the end-all be-all but I do still have all factions remaining on the map, some are rather larger than normal and some are rather smaller, but they are all still around. What I did to fix this was a sort of combination of mods and personal edits to said mods. Firstly I used the Character Trainer mod and Tyni's Bannerlord Fixes as the mods to fix this. Tynis Bannerlord Fixes is a mod that makes the leadership experience perks work for the whole stack and allows an edit to change the amount of xp given per person in the stack. I edited this number to double the native value so that troops in stacks will receive double the xp normally given by the perk multiplied by the number of troops in the stack. My next step was to use the Character Trainer mod to export, edit, then import every single noble in the game at the very beginning, before I even walked off to do the tutorial. In my edit I gave every single noble 25 Leadership skill, which gives them enough Leadership to be able to select one of the perks.
What this means is that now when a lord loses a battle and has to run around recruiting all those peasants they are able to actually train the peasants into a semi-capable fighting force provided they aren't promptly engaged in battle and defeated again. This has resulted in much more balanced armies and noble parties which means that the battles are much more even, or at least a little more balanced than before, so a faction that happens to win a single battle doesn't suddenly become an unstoppable force. This also means that the player is less likely to engage with a lord that has an army of 87 Battanian Peasants and 3 Highborn Warriors, instead facing armies that have almost no T1 troops and a much heavier assortment of T2-4 troops.
This leads to my suggestion now. While I understand that implementing the leadership perk, and subsequently the exact xp amount edits, may not be precisely in line with the thinking of everyone, I do think that at least allowing each noble to start with a minimum of 25 Leadership skill so that they are at least training some of the troops at the very beginning would be a massive step towards fixing the current snowball effect. Fixing the leadership perks so that the xp applies to the entire stack rather than to just a single unit would also be a massive step in the right direction I think but at the very least the 25 Leadership edit would allow the nobles to have a basis for training troops outside of hopefully surviving multiple battles enough to get a few decent men to keep the rest of the plebs alive long enough to train up themselves, resulting in more even battles during wars and helping to prevent the snowball effect.
