Holy hell, this will be a wall of text. A big wall of text.
First, some quick notes.
deathoftheflame, clense does nothing to death mark.
Dirty Arab01 : the firearm argument. A rifle could be used for hunting, for target practice, and to kill someone. A full automatic, silenced machine gun on the other hand can still be used as a rifle, but we all know that it won't be. It's just prone to abuse.
Kuroi86: The classification i like to use is:
Overtuned: Champions/items that are basicly fine, but their numbers are too high. (ie: Devourer in 4.20)
Toxic: Unfun/fustrating to play against.
Broken: An ability that breaks the normal flow of the game.
These three are three distinct issues, and you need either toxic or broken AND numerically viable to become a problem. For example,
is unfun to play against, but he's not broken, since you can pull an amumu/galio/karthus into your team, neither is he numerically strong.
on the other hand is both fustrating to play against (shield+nearly infinite dashes), AND breaks the flow of the game with his BS wall. While he is numerically weaker (and has a really low win rate), we still hate him.
is not the issue, she is a bit frustrating to play against, and not that broken. The problem is
makes her numbers go crazy.
is broken as hell (ult) and unfun to play against (ult again + passive), but her numbers are really low, making her a non-issue.
Whom i consider problematic:

,
. These are the good ol' pubstompers. You need game knowledge, and/or proper teamwork, and most importantly CC to stop them. Out of these guys only fizz and katarina are overtuned, the rest can be easily handled.
While
and
both have oppressive early games, if you can make it past the early game, their value goes down.
. Yep, he is an issue.
and
. I'll be honest. If you think riven is unfair to play against, you never seen a top lane karma/lissandra. While lissandra is a terror because she offers 4 CC in her kit, (slow on Q, snare on W, stun+slow on R), while offering good damage, and decent late-game. Karma on the other hand has an early game that makes lee-sin seem like a wuss. She has everything you don't want to see from a lane opponeit (AoE slow+damage, snare, shield, speedup, heal) and unless you have either nasus (slow+stupid sustain), olaf (cc immune) or irelia (cc reduced+dash+stun+sustain), you simply cannot touch her. Only the fact that she is mana gated during the early game, and has piss-poor scaling keeps her from being a permaban.
