Having played EQPC for a few years and now switching to EQOA, this is any easy question to answer. It's quite simple actually: timesink and a way to eliminate some of the reward gained by said timesink. Tunar that is "consumed" will need to have time spent to regain. Timesink = job security / income security. This is achieved in many ways, both noticeable and hidden by SOE. It is the way they make their cash.
