If you want to read up on the challenges that low and high level mixing generates in a gothic horror environment, I encourage you to look at the discussion here:

I'm reading through it, but 19 pages, it'll take awhile.
I hold to my initial statement. Role playing is a universal. Dictating who with, when, or how it is done isn't conductive to a good RP experience.
But there's no dictation, only revised distribution of rewards. Being that obsessed about the rewards isn't conductive to good RP either.
Dictation might not have been a good word choice on my part... here's an example to perhaps better illustrate the arguement I am trying to make.
Two 15th level PCs are invited to travel to an event in Zeklos Keep from say, the Cathedral in Dementlieu. The event is a debate between Torets. Now, the pair are taking their time, walking, and having a discussion about the theological impact of the actions of the Fourth Sect as of late. Its good RP, what they're doing. I doubt anyone would argue that.
Now, zone wise, as they travel, the systems percieved value of this RP will drop. From Dementlieu to perhaps Midway, they are fully accredited with full xp for what is a really good discussion. From maybe Midway to the eastern farmlands of Vallaki, they recieve half the old RP value of this discussion. Still not bad. From Vallaki itself to the location of the event, they no longer recieved anything. You can't say that the real quality of the discussion dropped at any point, while they travelled. During the event itself, a whole lot of quality role playing occurs, in which a number of important church events are discussed, planned, and decided upon.
Because the locale, which was perfectly suited for this event, is in a predominantly low level zone, neither of the two who travelled here recieved any xp. The quality of their RP has not diminished at any point, during the trip nor at the event itself. But the system has now applied a 'value' to that RP, where before it had a universal standard. These two individuals, who travelled to Zeklos, learned quite a bit from each other and from the discussion at the event. But the system has now decided this was not a learning experience for them.
Now had this all been reversed, if the event were held in the Cathedral in Dementlieu, they would of been fully accredited for the entire experience. And I'm sure thats really what the point is, to get these high levels out there. But you are putting a value upon their RP where previously, there was a universal balance. Thats what I'm trying to argue. You can't always dictate where RP is going to happen. You can hope, based upon the system and where the monsters are, but you can't predict where people are going to interact. Even the players can't predict that. We don't know where something is going to happen, when we're going to meet someone.
I just really don't like the idea of putting a ticket value on peoples role playing, even if its by location. Its like... next we should start checking their grammar.
I'm not really the kind to bandwagon anything, I wouldn't be doing it now but this has always been my favorite feature of PotM. Its what made this not just another server to me. I kind of hope I've made the point I wanted to say. Is this hitting home with anybody out there?
