Let's talk underrated champions

Ok, I am not a player that really enjoys pulling off flashy plays, nor cruising around the map with extreme mobility, dodging every skillshot that isn't random. I like non-LCS picks. I used to enjoy Viktor before he was picked in LCS, just like I enjoy most immobile mages and champions in general.

But this thread isn't about me. This thread is about champions that are seen as weak due to either not being picked in the LCS, or because of having low mobility/outplay potential, or even because they aren't picked anywhere, even outside of LCS.

I am going to start with , who will probably be my next purchase. This guy might not be challenger material, but he isn't weak by any means. He is quite hard to focus due to his ult, his passive lets him avoid falling far behind manaless champions, and his sustain is quite good considering he is a mage. Plus his ability to turn around ganks post 6 is quite satisfying, not to mention his heavy snowballing in general. I see his main weaknesses being low mobility, mana problems once he gets his ult, and a pretty hard to use AA if you want to last hit. But, anyway, he seems like a disgustingly underrated champion, who deserves to be reckoned with instead of earning his players an instant report from the LCS-copiers.

Anyone has an honorable mention? =)
