My vote is on: "Remove option to turn experience off".

Experience is a great feature, and I think it's ten times worth the CPU power it consumes. It prevents bots from ignoring new situations. If experience were set to off, bots would keep running into the crosshair of a human who has found a nice sniper spot. With experience on, however, after a few deaths they will choose a different path, and our camping friend will be forced to try something else.
