Map unlocking
The world bosses are pretty useful to have.
I use dragontimer to track them.

Hope that helps a little?
Hey wRaiz,
I noticed your post earlier regarding some map completion/unlock. There are various reasons as the why this is help and convenient listed below:
-Map completion rewards, whether for the enitre map or just one particlar area there are various rewards and lots of exp. for 100% one map and some of these rewards are only obtained through such.
-Waypoint access, having access to multiple waypoints is simply a convenience. There are many different aspects of the game spread all throughout Tyria (World Bosses, Materials, Dungeons, Mini-Dungoens, Jumping Puzzles, Guild Missions, World Events and more). Although many of these might not be desired/required now, there may be a point in time where it would be convenient for waypoint access depending on your future goals.
-Dailies, every day at 8pm (est) there are daily resets for rewards giving you multiple tasks to complete within 24 hours sending you although random places in the map. These give you rewards that a valuable over time and as well as 2gold for completion of 3 dailies.
