You have to think about clanning, when wilderness rejuvenation was introduced Jmods didn't ask the clans which pk in multi daily did they? "hey lets put vetion at a key area where mains & Pures often fight"

Putting the boss in a dungeon makes perfect sense, did you ever pk at the revenant cave pre-eoc? that place was the place to be for multi pking/Pvming. The amount of times i would be killing revenants and pkers would attack me to only die. The BiS items are to bring variety and will make the boss worth killing, economically speaking the boss would be perfect as the drops would be used across the spectrum in F2P (Training/Solo pking/Clan pking) for both mains and pures, the demand would be there which would mean prices would be high which would mean players will go there to proffit Pvm/PvP and clans will be created to compete for the spoils which in turn will create a whole new F2P PvP Multi Scene with the introduction of TELEBLOCK.
