Guild Wars 2

It is quite clear now that the continued issue with this game is that not completing events are more profitable than completing them because they offer concentrated numbers of mobs on a reliable schedule. And those mobs drop loot. Massive piles of loot.

As such, if ANet wants people to complete events rather than sit farming them in a uncompleted state the loot as to be moved from the mobs to the completion award.

They’ve somewhat done this with the Tequatl revamp. I believe you only get the champ rewards you’ve killed throughout the fight if Tequatl is defeated.
