League of Legends: Kassadin tops Patch 9.24 mid lane tier list

Buffed Champions

Diana

The rework to Diana in Patch 9.24 surprisingly didn’t move the needle in terms of her mid lane strength. Her win rate dropped by about 0.2% and she remained in the B tier this patch. However, there is a fairly high variance in opinion as to her strength level, so it’s possible she’s slightly underrated in the B tier.

Nerfed Champions

Akali 

Akali got a damage and hitbox nerf to her Q – Five Point Strike, which knocked her out of the A tier into the mid-B tier. Although her win rate remained stable from the last patch, it is among the lowest in her role (46%, which is third-worst).

Kassadin

He was a high-A tier pick before the nerfs to his Q – Null Sphere‘s cooldown and the mana restore on his W – Nether Blade, but even those nerfs couldn’t slow Kassadin down. He is the only S tier mid laner in Patch 9.24 and has a top-10 win rate in the role. Yes, his win rate (52.7%) is down from the last patch (53.3%) thanks to the nerfs, but it seems he’s still in a very strong spot.

Ryze

Finally, Ryze got a nerf to his Q – Overload in Patch 9.24 which dropped him slightly in the B tier. However, his win rate took a big hit, falling from 48.9% to 47.3% in Patch 9.24.

Methodology: These rankings were determined by finding the average standardized score of a champion from eight different tier lists from sites around the internet. This is done by assigning a certain weight to each different score, rank, or grade given by these sites (for instance, both a “Diamond” rating and “A” grade would be worth a 90 score). The standardized score is then determined by looking at the average score given to all champions in every role by that site as well as the standard deviation of scores given (so that sites that give out more high grades will not have their As be worth the same as a site that gives out very few high grades).

The full, underlying data can be found here. This link also includes the full listing of how the scores are assigned. Champions must be rated by at least half of the sites audited in order to qualify for our tier list.
