They can't even get what they've already implemented to work right. You want something else put in so it can have a brand shiny new error number attached to it when it randomly boots everyone and their close, distant, and everywhere-in-between relatives out of the game for no good reason?

The AFKers are a symptom of a very large problem. Fix the problem and the AFKers are no longer part of said problem. Hell I'd rather have people AFK all over the place taking up valuable playing spots than RMTers doing the same. An AFK timer is pretty far down the list of what's important IMO.
