I think it must be down to having a specific 'vision' worked out before the cameras start rolling. The director has to know exactly what he is doing.
With XMO: Wolverine, we saw just recently how much time and effort (and, no doubt, money and manpower) they wasted on all those designs for Deadpool. None of those designs were needed at all. Not one of them.
X-Men: First Class must have been rushed or they would never have allowed Fassbender's Irish accent at the end of the movie to be the final take. That was probably being done by some second unit while Vaughn and Singer tried to get the editing, FX and score sorted out.
