If they are trying to build a franchise with continuity and a sense of an expanded world, then just dropping characters doesn't really work unless their arc ends or they are written out by the events of the film.
It doesn't really say 'sequel' if a character is absent with no explanation.
Let's have an explanation at least. What's Fassbender's Magneto been doing all this time then? And why did he go to such lengths to break out Emma to fill what he said was the gap in his life, as he says himself. He might as well have left her in captivity.
