We need new events,

[Jojoya]

During WoW's Halloween event, the Headless Horseman will sometimes attack some of the low-level towns (I forget if it's on a timer or if someone has to manually start it, it's been a while) by setting buildings on fire and yelling incredibly hammy lines across the zone. This starts a timed event for players to use buckets of water balloons to throw on the fires and put them out while the Horseman lights more fires and taunts you. If you fail, he flies off and the event ends; if you succeed, he comes down to fight, but pretty much always gets instantly killed by high-level players, dropping a pumpkin full of seasonal loot.

The Horseman can also be fought as a seasonal boss in a special version of the Scarlet Monastery dungeon, where he has a very low chance of dropping his mount for players, among other loot.

But it would also be the exact same event year after year. Events did get a shake up in Cataclysm but other than that they didn't change through the end of Legion (when I finally quit WoW so I don't know if they've been changed since). There was always a vocal part of the player base asking for Blizzard to change the events and give them new content because they were getting boring.

The WoW and FFXIV styles each have their pros and cons. WoW events are the same year after year but the activities are more engaging. FFXIV gives us new stories each year and sometimes new activities but they're more basic and not as engaging. Both get boring after time.

I would give the edge to the WoW events though - the rewards would generally return each year so players could farm the event currency to get what they wanted from previous events instead of having to buy them from the cash shop. That tends to keep the interest in the activities going longer, at least among newer players if not veterans.
