The grind comes because TW decided to add not only a strange mechanic of having notables who are the only ones we can recruit from and who can die or lose power over time so there are less and less to recruit from. Then on top of that we need to curry favor with them and hope that they don't get pissed off at us for things like village raids by the enemy. It's a bad system that needs at least a revamp if not a complete overhaul. TW decided to add complexity without thinking about about the ramifications which seems to be the TW way.There is absolutely no thought required to determine -- without numbers -- if you should engage an enemy party. Ranged-heavy party. Approach at regular time compression. If the enemy party pursues, you run. If they flee, you engage. Every fight you take will be easy
You'd need for second system of determining power levels because the actual system used in-game for determining party power is, to be completely frank, naive. It likes to pretend mounted units are only worth 20% more than units on foot, when it is probably more like 50% even in bad terrain and up to 500% in some circumstances, i.e. horse archers versus a small party with no ranged weapons.
Ultimately though, I don't even think it will be more fun. Most posters here complain about the process of re-building their party and occasionally how long it takes, how it adds to the grind of the game. Forcing players to do that more often is going to drag down their experience because they have to constantly do the worst part, again and again.
