Swain needs some serious help :(

Being a swain main, i already had my issues mid lane and top lane but i learned how to manage with each different champion. This new patch in my eyes has absolutely destroyed swain. Fighting with a few enemy minions around, NOT anymore :(. Hey i nailed my W, run in E,Q,R chase, get bursted down because i have extra ravens but in 1v1 i have one that does 10% less healing. 5v5 yes got 3 people with my W, run in the middle ult, zhonyas, deal hardly any damage then get burst down. I dont know if i just am not building him right or if he really feels as weak to everyone else. I was gonna say at least i can fall back on my 2nd fav Cass so.......errrrrr wait nm :(. Guess i have to play ziggs until something changes. Anyone have any ideas??
