I'm actually liking new Swain!
With the last buff so that he doesn't need magic pen for his ult heal to work, he seems like a solid drain tank.
My biggest issue on old swain was that it was really hard to CS with him, but I actually farm really well on new swain, since his Q is great for farming, plus they buffed his auto animation and mana restore. The change of his ult to 5 ravens from 3 also helps his waveclear a ton.
His winrate is still god awful I think, but that might just be because a lot of people haven't embraced the proper skill order which is R > Q > W > E unlike the old E max first.
Anyway, I build ROA, Zhonyas, Abyssal, Spirit Vissage, and a situational last item and boots. I also take Strength of ages and run armor per lvl seals and MR per lvl glyphs for maximum tankiness.
Any Swain players care to comment on thoughts of new Swain? Anyone tried the tanky build yet? Is full AP with Deathfire touch better? Do you think he is still too weak and needs buffs?
