Why do people play _____? (Apart from being good at playing them, of course)

Obviously, for certain people there are certain champions in League whose designs and personalities are as dull as a bag of rocks. There's just nothing remotely unique or interesting about them to make you want to pick them up. For me, the champion that fits this most is . She's a girl with a sword. That's it. That's her entire deal. Yeah, she likes honor. So does every other champion of Demacia, that's just par for the course. Oh, she's rich, but her family fortunes were slightly disturbed at one point, that is not even remotely close to being on the same level as escaping from a gladiatorial arena with the help of a king who you then befriend and serve as an advisor to . And where another Demacian heroine manipulates light itself to blast enemies away and shield her allies, Fiora just has a sword. And the sword itself isn't even anything special. Like, how did she past the drawing board? Who looked at this champ and said "That is just as valid a character in our game as a floating tentacle eyeball that vaporizes living creatures as part of it's learning process." ? I don't get it, not at all.

Now that I'm done with my rant, what champion bores YOU out of your skull? (Please keep it to just one champion, or give shorter explanations if you can't hold back from naming more. I will not harass anyone for naming a champ that I find interesting, I will only give a short counter argument and leave it at that if that's what you want.)
