I don't think anyone takes major issues with Summoners having utility. It's just that Raise/Resurrection is such a jarring difference in utility that it solely defines many groups' priorities when building their roster or choosing jobs in large-scale content to play.

Utility is ok and encouraged, but Raise should not be the breaking point for someone to say "this job has utility" or not. Even in our fairly limited game design we have many utilities that aren't Raise.
