Riot should replace Riven's sword with a fork
Morton's Fork - TV Tropes
Because Morton is in the house.
I've looked at about a dozen threads going both ways, saying Riven is or is not broken, and they've all devolved into a downvote shitstorm. Clearly she's the Morton's Fork du jour. Likely just mentioning her will get this thread downvoted.
PS, the fork isn't making a pun about how quickly she can get fed. While it's a little apt, read the Morton's Fork entry if you don't know what that is.
