Many of you need to think outside of the box. Yes, it is very often that add-ons tends to follow the "help me play better" scheme, but it can go way beyond this. There are many things add-ons can help to reduce server processing/lag for the game client.

EVE Online has been doing add-ons that gives players methods to access game related information, w/o having to have a game client. ARR can have those kinds of add-ons as well. Non-game-client add-ons such as emails, events, LS/FC membership access, are just some of the possibilities.
