Long time lurker finally coming in to post. I've been wondering this for a while, and finally decided to post it. Ruin is stronger than Preservation. Much stronger if you include the Atium, though this may be negated by the Well. It doesn't change the fact that Preservation put more of himself into people than Ruin, which clearly made a large enough difference to have potentially led to the end of life on Scadrial. So that brings up the title question: Is Harmony unbalanced in Ruin's favor?
