i feel sad for swain mains
i was just trying out a HP regen build on nasus and after a couple of items the toplane swain could literally not bring me down 70% health.
edit:
alright so what i had was this

he had
and was working on Rylai forgot which parts he bought first.
i had roughly 150 stacks at the time and yes he had zoned me out the first 5 levels but once i had a few items he simply could not do anything it was piss easy to walk away from his W and his bird never really bothered me
kill wise we were both roughly the same till team fights started and i was about 20 cs ahead most of the game after lvl 7
