Suggested idea for the upcoming 6 star champions
This could be a perfect opportunity to use reskins as 6 stars (I.e. Dark Phoenix, xforce wolverine). These characters already exist in the game files from being used in earlier event quest. It would make it easy as they will still use the same move sets, but you will feel like you have a new character because of the change to their costume instead of releasing the same champions in every other crystal. You could also make 6 stars champions that are exclusive to being only 6 stars. I would love to hear what other people think as well.
