I'm not gonna lie...
I'd rather face release Zoe and a smurf Zed in Bronze 5 millions of times more than even a mediocre Fiddlesticks.
Legit, this champion is the epitome of bad design. He's almost every complaint the boards have had for the past two years rolled into one champion. Draintank? Check. Cheap, unmissable, high-damage poke? Check. Statcheck? Check. Massive, team-melting AoE damage? Check...twice (R and Q). Point and click hard CC that prevents you from diving onto him or anybody nearby? Check. Presses R>Zhonya's to win lane or teamfights? Check. The only way to make him fit more complaints is to give him double crit chance and make him speak in pseudo-Japanese.
At least when other champions are overpowered I can either just get fed as fuck and explode them, or they'll fuck up hard enough to let me win. If Fiddle is overpowered the only way to win is hope that his entire team is too stupid to clear waves.
His rework cannot come soon enough.
