I really don't understand the adding of the anniversary event tbh. This is something that I can't see most players doing more than 1 time just to get the rewards and be done with it. If it wasn't for the rewards, trivial as they are, I wouldn't even bother with it. Let alone revisit it every January.
They should have skipped it completly and spent the time on the necromancer, could have had it early next year instead of in 8-10 months
