The toon that earns the most achievement/activity points, gets the flying dragon mount, Heart of the Aspects. 2nd top earner will win the Swift Lovebird. The Armory website will automatically track your points, and will be used as the final tally by week.
EVERYONE of every level has an equal chance to earn points. One of the easiest, without even having to track them is pvp. Exploration, or dungeons are other ways. Check your achievements, load up on hot pockets and tasty beverages, and go!
