Some multiclassing feats look better than others. If we're going by this pattern you tend to get the lesser benefits multi-classing with Initiate of the Faith, Student of Battle, Singer of Song, etc. on anyone leading to leader classes, unless the later benefits are good going down that road.
Well it does answer one of the questions in my thread on martial characters using rituals, perhaps its better for some fighters to take Ritual Casting (and some possible skill training feats) instead of Arcane Initiate, as they may not be able to do the impressive magic stuff in combat, but might get a better chance at doing impressive magic stuff out of combat.
