The worst what I did was chop, chop... I load save the file, because of that and lost ~4hours because of that.
1. The prisoners will have a much lower chance to escape, especially when the game has the full version. Now they are escaping because we don't have many lords in-game and the chance for escaping is very high, especially when you are them not in settlement.
2. They too easy, too fast go-to health and get a group of 30 recruits.
3. This is realistic, you killed one, they hate you and they start a fight, so we have a war and only war with revenge.
When I start killing any lords I have two issues:
1. No one likes me. So get a vassal or something like that was impossible.
2. No recruitment options. I have a chance to get 5 recruits from town and 10 from villagers... only from my fiefs. When I started fights with others Lords I lost something like 4-8 recruits from one fight and 1 "veteran" troop. In one moment I get only 100 Empire Legionary 100 Imperial Palatine Guard and 50 Imperial Bucellari + 50 mix of what I get from prisoners, taverns and recruits. Ofc. with silly Lord who has 50% of recruits, I lost max 3 troops, but I was not able to replace that lost. When I attack a small army (180) I lost 13 of the most experienced troops. After 3 days of that fight my army starting lose more and more troops because I don't have 250+ soldiers, but 200+ next 150+ and simply I don't have new soldiers, not enough, they die too fast to replace the veteran troops!
Yes, I killed all lords from one faction, but after that, I lost everything, no chance to come back...
