As many of you know there are a great deal of zones that are virtual ghost towns. Sure you see a couple people who just got the dlc after a year of it being released and during the free eso plus events when people can do the content for free. But other than that many zones become empty. I have an idea on how to solve that.
Chain event quests set on repeatable server timers. These quests span the length of 3-5 quests. Example dolmen drops. You clear dolmen. Suddenly you get a world notification much like the cyrodil ones. Multiple dolmens drop spawning extreme waves of daedra. If you reach the quest set amount of daedra killed you trigger the final quest/boss. A very powerful world boss that requires you to follow certain mechanics similar to trial bosses. If you kill the boss before the timer ends then everyone who participates can loot the mega chest that has wonderful goodies inside. Like gold mats. 10k gold, the rarer zone drops and even pets/costumes. If all the major zones had these random timers that spawned these zone events it would definitely bring players to the zone. Especially if the rewards are worthwhile.
