Which is but one of the situations throughout the game's story which makes this whole retcon in EW seem... rather ill-thought out.
Granted, by the time Ravana was fought, the WoL had already started restoring the Crystals so I suppose it could be handwaved that "the Blessing was already being restored so thus was their protection from Primal tempering", but that is a real stretch. So my point still stands.
