I want more bandits to attack me during a ambush! not just 1 or in pairs but like 4 or 5 bandits at once.

If there is a group of bandits (Vilverin) with a ringleader I want that ENTIRE group to attack me at once.

Yeah, that'd make sense.

Although I hate that I end up killing more bandits by the end of the game than there are people in the land.

Also, turning them in for a bounty would be pretty cool (turning them in alive, I should specify). Sounds difficult to implement, though.

I'm always for more NPCs, makes fenzy/fury+rally more effective.

Later in the game when I'm a slinging powerful summons and massive swords like a badass, I think it would be very appropriate for me to be taking out large groups of bandits at once. At the beginning, though, with my "baby's first" fire spell and rusty kitchen knife I should be struggling to take down even one.

Ambush Book of Eli style.
