swain rework is just terrible design
champions are supposed to have strengths and weaknesses
swain is supposed to have weak waveclear and mana problems, but have high targeted burst
not all champions have to have 0 weaknesses and no counterplay

These three items are all good against Swain, and the healing on his ult is being nerfed in the next patch.
His damage is low compared to other mids, so magic resist does wonders. Especially since he usually doesn't build for penetration. He is easily kited since his CC is unreliable, he has no in-built mobility tools, and he can't use his ult's heal unless he's close to you.
Swain has plenty of counterplay.
Eh, I usually get some combination of
with 
Gives you AP, HP, MR, armor, Mpen, and mobility. You're practically unstoppable.
Swain and Mundo are easy to deal with, ADC's just need to realize
is more valuable then other items in games with either or both in them. most times i find
to be less useful then the garanteed GW from
cause with mundo or swain you'll have a hard time as an AP to get to the 40% mark due to both of their high health, high regen design. And its never a bad idea for top laners to buy
when the lane calls for it.
swain dosnt have and never had burst
