Agree with a few others that posted above me--unless you are pushing savage raiding and/or extreme primals when they are first released, the 35 points won't make or break either class. Either split them halfway or put them all into whatever class you use the most (mind for SCH, intelligence for SMN). Keeper's Hymn is always available if you find you could use the extra points.

I wouldn't use VIT since it will not impact healing OR damage on either class--and most content will not require anymore additional VIT than what you can get on gear (except maybe in savage, where those points would be better utilized in your main stat anyway).
