The real problem with URF isn't the fact that it makes so many champions busted OP, it's the fact that in regular non-URF play, those same champions are ALREADY busted OP. Some are obviously better for URF alone (Hec, Eve, Shaco, etc.) but try playing against Graves, Fiora, Zed, or Ezreal in URF. They just stomp everything, even the traditionally "good" URF champions, because all of the overloadedness in their kit making them unbearable in regular play is amplified by 10x in URF. Seriously, try picking Graves next time and rush Death's Dance like you normally would. URF or normal League: it's impossible to tell the difference with him lol.
