I love playing singed, but I think right now his kit is in a spot where any sort of significant buff to anything but his jungling power would break him. When he's strong, his kit automatically lends itself to proxy farming, which is a bad gameplay pattern. the idea of don't chase singed is fantastic and a great niche that only he really has, but the way proxy singed turns the game into a lose/lose situation where you can't stop him just by killing him, but if you don't stop him he auto pushes every lane indefinitely leaves the enemy team feeling absolutely helpless against him.
