You may have to look up what 'deterministic chaos' means to actually understand the question. I believe slightly differing initial conditions in wow may very quickly become big differences. If that is true, which I am not sure it is, then wow is a function of deterministic chaos, and there is no hope what so ever of predicting what changes the devs make to the game will ultimately become. If true even the devs would be helpless against this, as there would be nearly an infinitely number of variables to account for.
