Swain takes attack damage?
I've been playing a lot of Swain this season switching over from Viktor pre re-work and then Azir briefly before he got heavily nerfed. One trend I'm seeing a lot of in diamond through challenger swains is they add AD onto their builds to go with the E to get more early game harass.
Has anyone tried this?
I'd run hybrid pen but I lose a lot of mpen in the process and I'm curious how effective this strategy. Saving up IP for a new rune page to test some variations.
All aboard the Swain train. 
to help with last hitting. I've seen this a lot on Kennen, for example. It's a bit weaker since they changed it back to 3% lifesteal, since 3% of your ~60 starting AD is basically nothing.
