Singed's Fling bug makes him UNPLAYABLE.
Either disable him until a fix is available or hotfix him. If I cannot reliably make it to the back line and fling their carry to my team then what is the point of playing Singed? Playing ranked today made for some stressful times when I flung the enemy ADC and the landed right back in front of me, and not behind me. It's even more fun when I fling someone, and they go to the side instead of behind, making my poison trail completely useless since they're not even behind me.

(was my opponent) now it appears to be more than that
