Lord of the Rings had three 3 hour+ movies to tell one story. The Hobbit is hardly a reassuring example of a large cast film, as most of its characters, particularly dwarves, were forgettable or felt unnecessary (though perhaps they too will benefit from this being a 3-part story). Harry Potter films, to me, always felt very rushed and full of underdeveloped characters.
When people count the cast for X2 and First Class, those lists include characters like silent henchmen and non-mutants. Whereas DoFP combines two sets of the leads from two eras, with lots of fan favourites. These movies always had complaints about some characters not having much development or much to do, I rather expect they'll be doubled with this one.
