"i’d like to see ALL the attributes determine more, in fact."
That may be the case in Riftrunner. One of the peeks of the week mentioned the possibility of the Polymorph spell backfiring (changing something into a stronger monster) if the caster was not experienced enough. That may mean nothing (like the warnings of healing potions becoming addictive in Divinity), or it could mean spell results are effected by intelligence (or possibly character level or number of times the spell is used, etc).
