Paul Blackthorne should have been the main villain in the crossover. He did such a good job in the Flash episode, he deserved to have more screentime than that one episode.

Leonard Snart/Citizen Cold should of been in all four episodes. That would of been even more awesome.

Thea and William should of at least attended the wedding. That would of been more motivation for the group to fight the nazis, especially Oliver. Protect his son from them. And William can meet the Flash.
