Do 6 knights work?

Hi all. I'd been on a major winstreak playing basically the same comp over and over. Then the game kept throwing me knights - Poppy early, Sej early. So I thought I'd see how 6 Knights work. Early midgame I was doing fine with 4 Knights surrounding a Kellen2 with Morello and a hurricane on Ashe. Late Midgame, after completing 6 knights (rank 2s except for Kayle) with Jinx2 (Rageblade, Hurricane) and Lucian2 (Red Buff). I was brutally slaughtered the next three games and went out at 6th.

Bonus from Knights doesn't seem to do much later in the game. I was amazed how quickly they melted. I guess it's just 5 less resistance than 6 Nobles, with no heal, eh?
