It is quite exciting up to a point, that being, when you realize that the requirements for gold are quite easy. So just drop that AOE skills 2 or 3 times.
In the beta, people repeatedly asked for more levels of reward for people who did best or so. Like, getting platinum for being in the top 5 contribution to the event out of the 50 people who participated.
Why should someone who just walked by and used his AOE attack get silver, when i spent 25 minutes doing that particular even and got a reward just slightly better than his?
On the other hand, i remember reading Anet’s stance on this, and they mentioned that they have no intention of changing this around.
