Agreed.

Just finished a title where I had to make that exact call - the character
controllers were very expensive to run and we had large character counts.
Removing character controllers from most NPCs (and using a few simple
raycasts instead) solved the problem nicely, and the pathfinding picked up
the slack.

Tried a distance based LOD scheme on these too. Proved unnecessary though.
