Honestly, if you don't feel motivation for the RP, there's not much you can do about that, I get it, I feel the same with a lot others too..
But yeah, if you want to leave, at least make it seem natural, both for the rp and you, nobody wants to have the reputation of being an "RP killer"
The RP is generally moving really slow, because the one in charge is AFK permanently it seems.. So we only have the end objetive really clear to us right now
I do however think, our next objective would be to try liberate Falkreath from the vampires? I mean, we could decide ourselves really... I don't see any way fighting in Falkreath would change the story too much..
