Re: X-Men: Apocalypse coming in 2016!
Sure, the younger version of Prof X, Magneto, Mystique, Beast, Cyclops, Storm, Jean and Wolverine could face off Apocalypse but the older cast (who have fought more villains/events in this movie series) just looks more experienced than the First Class cast/the younger version.
And in Evolution/TAS, the X-Men weren't exactly amateurs and inexperienced, they already fought with a lot of villains/mutants before they fought Apocalypse.
