I don't go by the sewers very often, so I missed that.
RPing in place at Harns or a Tavern will cause a citizen of this- or any- realm, to miss all kinds of things. (Not neccesarily applying this to you, it is just a general truism)
There is a balance that needs to be realized between leveling/fighting, questing, PvPing, and RPing. IMO the game is best when ALL are used to their fullest potential.
Fighting on the move- once you get the hang of it- is FUN. Questing (when the NPCs cooperate), is FUN. Dueling against players of equal(or in my case greater cause i like a hefty challenge) skill is EXTREMELY FUN, and you add in the IC RP on top of it, it's what separates PS from the rest IMO.
PS- if properly realized- will be the best of every world.
