We can't expect the Roleplay XP in the outskirts to not be restricted when there is level 17+'s in the outskirts waiting for those poor AMPC sods to show up and nuke em. It's frankly sad to see good roleplay get destroyed by higher levels needing to flex. Honestly I think the restriction could stay as long as this is the case, and maybe there is a way for everyone of a level 10+ to agree upon hanging around VoB or even port? Dunno, just my two cents.
I generally think it's bad for OOC considerations to dictate IC behavior. Although in a way the RP XP throttle is an OOC mechanism for pushing IC behavior, I rationalize it as an experienced person isn't going to learn as much by hanging around with inexperienced people all the time.
If, however, the PC has motivations for being in the Outskirts--and a motivation could be she likes to watch over it and protect it from things that go bump in the night--then it would be OOC to make her move.
As aprog said about closures, some practices need to be cultural, rather than rules based.
Iridni doesn't lurk in the Outskirts. She will go there to place Kinship recruitment posters or--once in a while--with another Kinship member to patrol because of an ongoing investigation. But she mostly stays in the Lodge when not involved directly with something.
Whatever the throttle is set to, it's unlikely to affect her behavior, but it does seem as though it is an IC-justifiable incentive for a PC whose sole drive is XP and power levellng to go elsewhere. Hence, I have no problem with it.
