Here is my feedback for this event.
The rewards are too low to break off important farms.
Why should the average player want to stop their personal progress to more efficiently complete a global goal that would help other guilds and players if the others don't necessarily have to do the same thing to earn the rewards? It puts an individual in a worse off state and helps their direct opponents (in GAC, TWs, arenas, etc) who maybe chose not to work towards the goal.
If you want to hand out more rewards to help parts of the economy, just do it. Buff rewards for existing events or create new events for us to play. As it stands, with the current iteration of this event, this is kind of like the prisoner's dilemma except the best case for everyone is to just defect. Straight up ignoring the event is a significantly better ROI for everyone involved so it makes the event feel pointless.
I think something like this would be better if it had a non-trivial personal requirement to earn rewards (so you know everyone has participated a sufficient amount towards the goal to earn them). And the rewards at the end need to make up for (and exceed) the loss in progress needed to hit the non-trivial requirement (in order to encourage players to work towards it). If these are decided to be improvements and they are implemented, I think you'd still be hard pressed to break the point where global cooperation in order to earn the rewards exceeds the potential gain from defecting if others were to fail and your farms not hindered like their farms could be. And SWGOH players would likely start holding off on investing in the event until the last moment when it was certain to succeed or likely to fail.
The current iteration is, in my opinion, not it. But I'm also not confident any iteration of something like this is it either, especially without in game integration. I think you would probably be better off doing global events that are based on guild events. Maybe you run a global krayt raid and we need to slay X dragons (full win, not just submitting a score) in order to complete it. Or a speeder bike raid and we need to defeat Y troopers. Or maybe even reutilize some of the guild activities (like squad arena attempts, cantina energy spent, etc) but at a global level.
