I'm still willing to pick Heimer into Leona and wait it out. She'll eventually get impatient and go in and I'll slap her shit around. He's the only other champion that I'm able to take bottom and feel good about the matchup. I don't really have anything up my sleeve for Thresh but his ban rate is at least creeping up. If there weren't so many ridiculous junglers there might be space to sideline them both for a while but that's just not the case. Kha, Vi, Elise, Gragas, Yasuo, Kassadin are all getting benched ahead of them and for good reason.
I really don't understand Kassadin. Riot has a history of nerfing the absolute fuck out of a problem champion in anticipation of a rework (Olaf, Evelyn, Rengar) and Kassadin gets to skate by with a 90+% ban rate in solo queue and an almost 100% ban rate in LCS. Even if they truly believe in their heart of hearts that he's notthatgood the entire player base has made it perfectly clear they do not want him in the game in his current state.
