Since word counts are a pain and there is no edit on phone.. IMO, for ps4, as long as you can maintain your mp, ruin 2 is much nicer to have in an easy to use place. Make sure the fairy is in stay/place and it's sooo east to kite. I've pulled through some nasty near-wipes by dragging mobs around while using bio/energy drain/ruin 2 to finish them off. Also good for running in to help kill adds when your dots won't have long enough to tick.
