I know it's unlikely but as someone who's been playing since 2017, it's rally annoying to only have half of sets like the bone crusher set because you weren't aware it was time limited. I have the scars, tattoos, eye-patch, hook, peg-leg, gloves, belt, and boots. But the hat, jacket, dress, pants, etc were all time exclusive, something I wasn't aware of at the time.
I think, even if it was only for a week or one event on each day in a week, that it would be cool to experience the old events again because they were a lot of fun and because it opens up access to time limited items again. I know items like that are often more of a status symbol for players who were there for the events and that's why they were made time limited, but having to match my bone crusher items with other items because I cannot get the items anymore is frustrating.
I'm personally biased because I really like the set and because the only reason i wasn't active was because my computer was broken at the time so that's additionally frustrating, but I really think getting to experience events I wasn't around for would be a fun experience.
