A note: More enemies are healed by an element than those which also bleed that same element, so it's not just enemies that bleed an element which are affected by it.
But more to the point - if that is the case, and built into the code is already a safeguard to prevent healing of an enemy via Elemental Ranger, than I suppose no change is needed to it. But how many people never took that talent because they didn't know that? This may be a lack of information causing confusion, and all it would have taken is a short post from a Larian guy to clear that up.
