Is it the player or the champion that sucks..
Look, I'll be the first person to say I'm not going to be in the championship spotlight anytime soon. (maybe two years). But I've had countless people, and I REPEAT Countless times people say don't pick a champ because he/she isn't great. Lets talk about Jhin for example. With the exceptions of possibly crits and his E, he doesn't have escapes. However when <Teemo> Teammates like this say he is a bad champ and you go 10/0 with him. How the hell is that the champs fault? Like I said, I'm not the best Jhin player on the planet, first couple games I sucked with him, however I came to an understand about his strengths and weaknesses and found to <Teemo> anyone off in a teamfight.
