You guys (Arenanet) made a big effort to make players want to help each other out and cooperate. Whenever someone is downed or dead, it is marked in the compass and the world map, and a big marker appears over the character’s head, and rezzing the person gives an exp reward.
It seems to be against this philosophy to NOT have rezzing event participants contribute towards your event points. The players who take the time to stop attacking the boss and help out their dying comrades can end up with bronze medals as a reward, while the players who ignore their dying comrades beside them and continue firing at the boss end up with a gold medal.
I would like to suggest that resurrecting downed and dead fellow event participants contribute towards our event points, too. After all, when we rez someone, we’re bringing reinforcements back into the fight—that IS a contribution and should be counted as such.
