As things are right now:
Cursed shores are no longer the place to go to farm. There are rarely enough people to do temples or events with on most servers. The only real reason to be there is personal story or arah.
Suggested Change:
Dragons.
Several locations around cursed shores where every hour there is a chance for a lesser dragon to spawn there. With a drop of 5-15 dragonite maybe this would allow people a way to farm dragonite without going back and forth on servers finding world bosses.
During arah story mode there were tons of dragons you fight before the big Z, so wouldn’t it make sense? The fights wouldn’t have to be world boss size, because it would be nice if they were more mobile.
With this kind of thing to draw people into cursed shores, I believe temple quests would be more convienient to do and you would see them being opened more often.
Just a thought
