[Possibilitas]

I rather like it, to be honest. Running is an option if you stood and fought for 10 minutes. This doesn't really start to become an issue until you get up further in levels, and only if you have particularly bad luck. If anything, I say leave it alone--a mounted paladin *should* be a terror to fight. Paladins in general are rather weak in NWN X games, having the black little hearts of our characters tremble when a paladin turned fanatic is riding them down just seems peachy to me; if not a sort of karmic-justice. ;)

If I were to recommend a change, it'd be that paladins do not attack good-aligned characters unless first attacked by them as they can Detect Good at will.
