This is the best they could come up with after several months of delays in order to provide us more info...
We get an update that severely lacks any info about the event, how it works, when it starts, the rewards, or anything else other than a generic hey we plan to do this thing sometime maybe 2021...maybe 2022 if it is delayed again...
There is no reason they could not have told us this 6 months ago unless they were not working on it back then.
I have a gut feeling they were not working on anything at all for the last 6 months then last week they all scrambled and came up with this empty promise with no details because had to say something to keep the little bit of hope alive.
Honestly I'll be suprised if we get this in 2021 and if we do it will provally be dead and neglected within 3 months after release just like the bug tracker.
Pathetic RA even more pathetic of a delay to just come up with this bare minimum RA containing essentially no real information about the event other than it's like GAC but vs Ai.
