Yeah, I've read that topic, but I was left with the impression that Minsc should / will acknowledge Valen for what she is and not stand her for long, so...
And getting back to Ano, I hardly ever use "Turn Undead", so that wouldn't be such an issue, although it might be just me - it's indeed an usefull little thing to have at high levels. Still, don't consider CHAR_NAME's fellows morons -] neutral Anomen (or TN Viconia, for that matter, or a non-evil PC cleric) knows his party members and is not likely to turn Valen while fighting back to back with her, for no other reason than he'd get his back unprotected should he do it, and although chaotic he's not suicidal (aka the player has the choice of keeping Valen waay back, fighting in five AND turning or fighting in six AND not turning).
The fact is, although all this compatibility issues can be explained one way or another (good / neutral clerics can turn Valen, Minsc is so dumb he doesn't realize 1+1=2), they don't make sense. Shouldn't they?
