Yikes! Totally hadn't meant to open a can of worms with that one ;)
I've no issue with XP coming from Parley per se. My players were doing it a bunch, half because a few of them were being just plain disagreeable, and half because one player in particular was trying to game being disagreeable to gain more XP. Said player, the party Cleric, was largely holding out on healing until folk supplicated his evil god of suffering and blood. CLW was his leverage over allies, trying to get them to do more and more worshipful activities, and he was trying Parley any time there was resistance to it. Largely to game XP for his allies. In addition, he was also having his character be a stick in the mud about pressing onward in a couple ways in the hopes that he would be reciprocally Parleyed.
Again, after I mentioned "Er, guys, we've been playing for an hour and you've been asking every couple of minutes to Parley, can we get on with the adventurin'?" the amount of disagreeableness went down and it wasn't an issue so much.
All in all I was just curious about that XP grab sticking out there when the ways to get XP had been significantly hacked down to more theme addressing things. I saw mention above that 15-20 XP a session wasn't uncommon in some parties, so the drop to "1-4 plus however many times you twig alignment; oh, and Parley," just made the XP mine of Parley seem a little... out of place. I don't see easily better options for it either, outside of ditching it and bringing back "Order Hirelings" or something as a replacement. I like having Parley, though, so I'm not too concerned.
Anyway, off to make some Dungeon Fronts for Keep on the Borderlands. Cheers :)
