I've been buying the manaless champs recently, because they can be really easy and fun to play, but I can't decide who did to get next, between Riven, Renekton, Shyvana, Rumble, Akali, Kennen, Lee Sin, Shen, Vladimir and Mordekaiser, who would you say is the funnest. I just don't want to blindly buy and champion and find out he/she sucks.

Lee Singah

Lee sin is really fun

Warmogrina.
Pentakills left and right unless you're brain dead

dat grammar

Vlad. Because it's fun to just smash your face on the keys and get triple kills.

you forgot katarina. She is manaless and have resets.

lee sin's very fun

Mordekaiser is my favorite faceroll champion.

@draztikk Those are the champs I don't have, so I didn't forget here. Also I agree, she's really fun
