As I mentioned on the Beta forums and GD, It doesn’t matter the number of anniversary.

This is a live game, We should have some new rewards, something to buy with timewarped badges via good gameplay.
At least the anniversary has more content that other events: A specific BG, World bosses, XP increase.
However, It still feels like something left behind.
OW 2022: New Skins
Maybe something like DBD that includes new mechanics each anniversary for some cosmetics?
Or We can even check what other MMORPGs do for an anniversary event:
Who could imagine a new questline for some reward in a MMORGP?
I already mentioned this before, but if quest designer worry about players doing quest, focus on side quest:
the main storyline could be skipped or rush during an expansion release, so maybe if you provide a good questline on events when there’s not a big rush for endgame content.
WoW anniversary has just a little bit of gameplay and for some events almost nothing besides a really low drop, while other games actually update events to bring players back for some rewards and activities.
