Who else is loving Swain after the update?

Mained him before the update and I have to say I'm loving it his changes. Since the update I have started maxing R>Q>E>W. I hear a lot of people are maxing W second but I would advise against. The reason being is that he is still a DOT mage and his W is just flat damage. You end up doing more single target damage by maxing E second since it is still a damage over time spell I believe. The only time I would suggest maxing W second is if you or your team needs the wave clear. I like building ROA, Sorc Boots, Abyssal, Zhonyas, Void Staff, and Death Cap. What is everyone else think of the new swain and your builds?
