Singed fling on Gragas (bugged)

Well where to start When you are going after gragas to fling him if he uses body slam (which he most likely will) you will take body slam damage as

singed your fling will go on CD and you will deal no dmg and he will not be flung on top of that you stand there in front of him not dealing any dmg while he

gets all the free dmg trade off.. say you where to turn around and try to get away he has more then enough time to slow you with barrel use drunken rage

and cask. please look into this thankyou
