It's funny, with holiday events, once you have something pretty good made, most players are fine with repeating it every year if you just add a couple new items to it. Especially when compared to "talk to 3 NPCs".
I'm genuinely looking forward to Shadow of the Mad King (Halloween) and Wintersday (Christmas) in Guild Wars 2 and I don't even play the game that much. I still haven't bough Janthir Wilds. There are plenty of different events on relatively short timers, all of which give rewards. That way it's easy to skip one thing you don't like and focus on something else. Or if you're going for achievements/weeklies, just do that thing a few times then focus on other stuff.
