I wonder if there is a single worst champion that people will agree on...

feel free to be as verbose or glib as you like. I personally don't think anyone is a bad champion, and I enjoy playing champs that people underestimate or think are underpowered. (I had a lot of fun with Karma this week )

Nocturne.

Skill set is too strong and kills the fun of the game.

ya i agree with above , nocturne's imbalanced. i just groan whenever i see a noct on the other team. i honestly have no idea how riot thought it was a good idea to give a champion tf's ult, fiddle's fear, sivir's shield, and yi's steroids. it's ridiculous.

another one would be cassieopia. really lackluster for a caster. she's almost like a crappier version of urgot, which is even worse since urgot's not that great to begin with. her ult's pretty meh too.

Pantheon, completely underwhelming and the success of him is based on the idiocy of the opposition. If they don't build any HP/Armor, overextend and refuse to interrupt his HSS he can work I guess. Otherwise he is just ****.

idk why but i just don't like malphite he has great abilities and passive but when he is free to play *GASH* he is brutal to people who don't know how to play him or vs him

I <3 Urgot
i agree with slim Jimm he is never used,
that is probably due to him being really dificult to use and get into for a 3 k champion
maybe if he was 1.3k ...

urgot's easy to use. and the thing about urgot is that his late game just sucks, and does almost nothing in team fights. he has decent utility but he's utterly trash mid-late game if he doesn't get fed early game, it used to be fairly easy to get fed early game with urgot but since the nerf he no longer dominates laning and ganking phase, making him an underwhelming champion.

In solo queue blinds, Galio by a long shot. He's an amazing counterpick in draft if he gets the right opposing comp, but gets completely shafted otherwise. Therefore, against a random team and with random teammates, you will rarely get a situation where he isn't shafted.

In draft, I'd probably say Fiddlesticks. His two damage skills practically yell "KILL ME", and his two utility skills do negligible if any damage. Oh, and he's squishy. And his ult requires him to run into the middle of enemies while being squishy. Great for pubstomping, but anybody with half a brain will pound that pile of sticks into tinder.
