I would like to suggest to push wq to the first saturday / sunday of the month.
Especially if you plan on giving the world quest better rewards than all the events from the last 3 years combined, it would make sense to give more people the opportunity to participate.
I know some people also work on weekends but i think the number of people working then is less than on weekdays and I think i speak for many players that simply dont have 3 hours of spare time on a weekday with work etc.
Usually it doesnt matter that much cause the Mysterious Ticket is nice to have but not that big of a deal, but 7 IV-locked Rerolls is literally by far more than ever before, probably more than every single reward ever given out in an event all combined.
Greetings
