Im kind of on the fence about this one. Gear score is just another metric and on paper can be a very handy guideline for players. How ever more often then not I have seen this particular tool misused to bludgeon other players.

Like Bharata was saying. We really need info on the mechanics of the system its self before we can pass any kind of informed judgment on it. If it's just a flat score assigned to gear regardless of its actual impact on your characters performance then I vote this goes out the air lock.
