In X3 we can assume that as a holy man he chose to live a more peaceful life rather than that of an X-Man but DOFP is a whole different scenario. If we assume he is idle somewhere else while people are dying...that ruins his legacy.
Eh not at all.
With that logic, you are saying that its okay if we see hundreds of NAMED mutants just because there's a war between mutants and Sentinels.
If he's not gonna get a big or substantial role in the movie, its better to just leave him alone.
