In the game of Marvel Future fight, there is a mode where you can challenge a World Boss. It would be a great addition to the game if we can have that for MCOC. For example, World Boss would be a game mode similar to what they had for NYCC beat the boss challenge. The World Bosses could be like: Maestro, Thanos, Apocalypse(if he ever gets added) Kang, the Collector, etc. I think it would be a great test of skill and a fun new game mode to play in between Quest, AQ and War. Just a thought.
