Guild Wars 2

Two suggestions here.
Suggestion 1
Enemies grant bonus exp based on how long they have been alive, encouraging people to hunt them in obscure regions of the map. Make this same effect apply to events. Things that never get done, such as risen giants or sharks, those generally considered too much effort for too little reward, quickly rack up the bonus exp and karma and gold. The nice part is its already farm proof, its kind of anti DR in a way.

Suggestion 2
This stems from a revelation I had about events compared to quests. The great satisfaction of quests and a quest log is seeing it empty and having that sense of completion. What if we had an event log? The format I propose is this:
Queensdale 0/60
??
??
??
…
Where the events are initially nothing more than ?. Alternatively you could remove the zone headings to reveal even less info. If you discover an event but don’t participate the name appears
Queensdale 0/60
Prove you know a lot about Destiny’s Edge(Not attempted)
??
??
If you partake in the event and it fails then it records that with a special symbol
Queensdale 0/60
Prove you know a lot about Destiny’s Edge(Broken Red sword icon)
??
??
If you partake in the event and it succeeds then it you get a star of the highest attained completion level
Queensdale 0/60
Prove you know a lot about Destiny’s Edge(silver medal)
??
??

Queensdale 1/60
Prove you know a lot about Destiny’s Edge(Gold Medal)
??
??

Once all the events in an area have been discovered and completed at gold you get a special star in the Event log.

Additional functionality for the event log could include favoriting gold medaled events so that you can see when they’re up no matter where you are, or event sets.
An event set would be similar to a meta event except it wouldn’t have to be progressed sequentially and there would be a special reward on completion. They could also span several zones, telling greater stories. For exmple there could be a centaur assassin event set which required you to attain gold on several events that kill centaur bosses such as: http://wiki.guildwars2.com/wiki/Kill_the_Harathi_overlord http://wiki.guildwars2.com/wiki/Kill_the_Modniir_overlord and http://wiki.guildwars2.com/wiki/Defeat_Ulgoth_the_Modniir_and_his_minions
