Singed: The Freelo Champion people have forgotten
Now, before anyone tries to elo bash me, I have no issues facing Singed, I know the lane matchup, and I'm not low elo. I know simplistic champions like Singed, or nasus, when someone complains they are just spouting off low elo nonsense, but I believe if any other champion currently had Singed Massive winrate they would immediately be nerfed.

If we look at the stats, right now, he's by far the strongest top laner (with a 56% winrate and 3% pickrate), and this is in spite of his hardest counters being meta (the likes of lulu, janna, and other mobile hyper carries like tristana). Multiple singed one tricks are climbing severly higher than they were pre-rework (singed420 going from plat 4 to challenger in all but a month) and his platrate has also increased by about two percent.
I don't know about you all, but this screams blantantly over tuned, and the only reason he hasn't been seeing traction lately is because he has a very specific playstyle unique to him and him alone. I fully expect him to be pick ban in a patch or two.
TL:DR Learn singed while the gettings good. I promise you he is on the level of janna right now, and will be getting nerfed after his hard counters are nerfed.
