Pug Matching, or "What If Blizz Had Us Fill Out Pug Personality Forms?"

This is just for fun.  It's not an actual feature Blizz is implementing or considering, though it might be a good idea someday if they throw all realms into the same pug system (instead of doing it by battlegroup).

Non-Gamer's Guide to This Post

If you leave a character in an inn or major city while you aren't playing, they will be "resting." This means that when you get back to your character, they will get 200% experience from all monsters that they kill until a certain point. The longer you rest, the further along your experience bar this "point" will be.

You do not lose your rest at any time, and there is no "window of opportunity" to kill monsters. (It is not timed.) Quest experience just bumps the resting point up (quest experience never counts toward your 200%, but it doesn't interfere with it, either).

There is a cap at ~2 levels.

The 200% experience is gone when you reach the marked point on your bar (the bar will be faintly blue and will say that you get 200% normal experience when you scroll over it). There are no tricks to it. It doesn't disappear if you log out before you've reached the marked point.

This was implemented to help players keep up with their friends even when they can't play as often.
