Don’t make this only viable by the Lost Shores “mega-event”! Allow players to do so once per day! Like a meta events that starts In a town and goes around until a huge dragon stomps Rata Sum and It goes down to ruins. Then, a nonstop events starts there telling players to collect the debris and to help construct Rata Sum again. Or a mad Quaggan appears out of the blue yelling nonstop THE WORLD IS GONNA END In Lions Arch, until he’s pulled from a dark presence…. then players chase said thing down to a portal, fights shadows and all minion dragons possible… until that mad quaggan transforms into a dragon itself and… meh, you know the rest.
I don’t mind repeating said events, tho… If It gives players several ways to deal up with the situations and possible “endings” to It.
