I think you have a case of the flavor of the month. As Shanco pointed out, you did amazing with an unconventional champ last season, Irelia. In the ranked games in your match history, I'm only seeing you play "top tier" picks. If you're just playing them because other people tell you they're overpowered and must-play champs, you should avoid doing that, and instead play champs you actually enjoy playing. EVERYTHING is viable, don't let anyone tell you otherwise. Yes, even Urgot.
Again I'm just assuming.
Also, don't solo queue.
