Curious, what specifically is annoying? To me, 2 things. (1) the NPC groups should organize better in attack. Cuman and bandit camps are relatively easy prey for Henry before and during Ruin and related quests.
On horseback, Wolflin’s whole camp was pretty easy to cut down solo. Want a different way? Hop on the wagon in their camp… near invincible.
Enter Pribyslavitz in controlled manner. Possible to kill every single enemy NPC… on a ‘sabotage’ mission
(2) when weaker, one strategy is to have Henry draw the enemy NPCs away from spawn point to isolate and hit and run. After a while, the NPCs quit and put their weapons away. No defensive position, no tired position (hands on knees), etc. that makes them execution targets. not cool.
