I want to add my thanks for the event. It definitely harkened back to the days of the very first Winter Lord event and I did with this one what I did back then: Level up things that I thought sounded cool on paper, but could not bring myself to play for an extended period of time at low levels. This included necro-alting a few characters from 2019.
Now I just have to slot them all, but that's the fun part. Thanks for your time and efforts!
