I fear this got burried - I think it is highly underestimated by devs what visible progress does to motivate players.
So far this event is rather a disappointment, sorry, the green bar is not really moving, points are “doubled” for a week (means in fact, devs do the event themselves since community alone is not willing or able to…).
What are we putting all our stuff in for, what should we farm for after personal rewards are gotten? It does not look like contributions matter, the island will be released when it is decided to be released.
Now IF there was a leaderboard to at least see who puts how many, or even guild contribution like in the last event, this would be major, major incentive to go on with that. It would be fun to compete with others and that is a reason to put playtime in. If points are just going to nirvana like this, no-one will see them but you, yourself in your book and perhaps the handful you screenshot it to , it is just a waste of resources and time to compete, just my 2 cents on this.
(And I am a major contributor despite, at least I hope so, no-one can really know since others points are hidden… still not giving up hope that this is added soon).
