I don't feel like Singed's damage happens fast enough for modern day combat scenarios.

I love Singed, and play him whenever I'm in the mood for it. Some days, if I can get matched against people I can run around enough, I can even do okay with him, get a few kills and all that. If and ONLY if I get matched against someone who is either not bursty enough to push back or not mobile enough to easily escape.

But the thing is, that's really rare, to be in a fight against another champion and they AREN'T dealing more damage in a trade than i can deal out by getting them to huff some toxin, or leaping and dashing around the battlefield so much that you can't reliably keep them in the toxin.

I dunno, I'm not a good enough player to put it in words that will convey everything properly, but Singed just... he kind of relies way too much on long slow protracted duels to deal any sufficient amount of damage. In a quick trade off, his toxin just doesn't hurt the enemy big or fast enough to matter much. By the time SInged can build enough items to make his damage at all meaningful, the game is practically over. Same applies to teamfights, Singed can only really deal relevant damage in a teamfight that's at a stall, where he can run around the battlefield keeping toxin clouds in play. A fast-moving stun-slam-dash-and-nuke and done teamfight, which is MUCH more common to see in modern day League, gives Singed little opportunity to meaningfully contribute.

Very few champions, I'd even say almost nobody, in the game right now is slow enough or non-mobile enough to stick around Singed's toxin clouds long enough to matter. He can pull a Teemo and get them softened up with some Rylandries comboing, but to actually successfully kill someone on his own? When there's a glut of mobility and all the priority targets have escape and counter-initiation skills that move faster than Singed's good ol' traditional foot speed? Eh. It's just not happening. And that makes me sad.
