Actually there was a petition to add the lines from Junk's Revenge into the Halloween skins! Jeff said that should be going in November. And yes, I would get SO triggered lmao.
Hard mode is HAAARD @_@ What made a huge difference for my team was changing the strat during the first Junkenstein fight. Let Junk spawn, but instead of McCree blowing his ult, wait for the Reaper spawn a few seconds later. Then have Ana ult McCree, use High Noon, and they'll both go down.
