For 3-4 days I worked on lords to have better tier troops. It will be at beta branch 2-3 days later with other developments :
Here is latest situation after developments, as you see tier1 / tier2 troops are generally 25%+20% = 45% of all troops. It was 45%+25% = 70% before. Also now NPC lords will be visiting settlements & recruting more to fill their party size (more compared current version). Previously they were going enemy lands more frequently with less men (currently using 60% of their party size in average with additions this ratio will rise 80%). Also if they have lots of wounded troops they now go settlement and rest more. Armies will care their food more (they were dying because of starving much and their food management is a bit developed). Sally out exploit (if you lay siege with neutral army thing) will be gone. You will not be able to change troops of villagers / caravans / militias with donate troops option. NPC lords will make better economical management, if they are rich they will recruit more and increase party / garrison sizes (this was already at game but developed). All these improvements will be at beta branch soon (2-3 days).
after developments :
before developments :
Also decreased lords escaping probability by 25% / 50% (from mobile party / from settlement). This will be later decreased more when replacement heroes are added to game. Currently it is risky to reduce very much because replacements are not added and some clans only have 1-2 lords. This addition (slightly decreased escaping probability) will be at beta too 2-3 days later.
Also you will be able to hire a caravan including better troops with 50% expensive initial cost and daily wage. However party size will stay at 30. Later new perks will be added giving +5 size to player caravans. I tested latest situation in lots of different save games and still caravans are very good value and travel with very low risk in most cases. I think we lost lots of time discussing this 30 thing. It was something needed and minor compared to other issues. People overreacted it before testing / playing enough.
