So far, I've gotten Cultist, Dragon and (unfortunately) 80s. Still aiming for Dracula, Helsing, Dr. Junkenstein, and Witch (the last two can be purchased with the saved coins I have).
I'm currently debating on whether or not to gamble yet again or hold off. I like the Dracula skin, but I also like the Shiver skin during the Christmas event and the Plague Doctor skin you can get right now for Reaper. Meanwhile for McCree, I got his "America" skin while also looking to get his younger self skin that was during the uprising event.
Gamble on more boxes? or hold off and either get what I can get later or already have? I guess I still have a week and a half to grind to help "influence" my answer... (still don't have the skins for Mei, Ana or Torbojrn, but I'm happy with what skins I already for them already).
