It depends which character I'm on and my general mood at the time.
In any case, the end goal of me spending time here is for my enjoyment - period. Sometimes I like having fun by chatting peacefully for an hour or so in Tau-23 with a BDM 'rock enthusiast', and sometimes I like having fun by forward-gunning a Scylla at point-blank range in my LSC, or SNACcing things in the beautiful piece of engineering that is the Orchid.
Basically, to answer the question outlined in the first post from a personal point of view: it varies anywhere from totally focused on the RP aspect of an encounter, to merely coating my PvP intentions with the required veneer of RP to let me start taking things apart within the boundaries of the rules.
