Can someone at Riot explain Nocturne to me? Justify him not being gutted until his rework in six yrs

We did the assassin rework to get rid of shit like that, we go on and on about how unhealthy statchecks are, and how unhealthy feast or famine is, how unhealthy mindless one shots are...

Why the fuck does he exist?

And it's not just low ELO either, he's commonly picked in LC$ and high ELO because of how absurd he is.

But hey, he's flashy and his ult is exciting for LC$ crowds, so nevermind. He deserves to be buffed actually.
