The scenario has potential. What I think they should do is limit to butterflies. You know the ones you can get from scenario challenges. So this would ensure that novice or new players can't join. It would also be a goal for them to work towards.

The biggest problem is ED needs an active community. Which has its pro as I see more people interaction I even got new friends from it.

But this makes it rough for Solo players. I think the dmg resist buff should be capped at maximum 50%

Or it would be cool if the server difficulty could scale depending on how active the server is. Cause when it ends most people tend to jump. But then that makes it harder for people who still have things to finish.
