Seems worst than before. The rewards completing is actually a lot less than it was before for completing given the required number of people to complete.
It has a 'small chance' of getting slightly higher if everybody in the guild completes.
But before not all members are fully active, so the completion requirement was reduced based on the active members. And you still get a higher amount.
So in a guild where only 1 person was active and you complete the quest, the reward was significantly higher.
Not sure I like the new system. I like the fact that it auto completes at the end of the day so that you're not stuck because of some guy who didn't finish his.
But overall the system gives you a lot less reward and requires too much of you.
I got "Nord" as a quest. Ugh. I can only imagine how annoying it is to be in a guild where everybody had to do nord.
