Gwen

Base Armor decreased, and Attack Speed Growth increased. R slow decreased at lower ranks.

“Gwen is still very powerful in the hands of experts, especially pros, after her reshape in 15.6. While Gwen players have enjoyed her newfound agency in lane, we want to ensure she has some weak matchups and can't simply flip the script at level 6 with a guaranteed chasedown. We're delivering some compensation so as not to pull too much power out of her kit.”

Irelia

W AP Ratio increased. E cooldown decreased at higher ranks and AP damage ratio increased.

“AP Irelia is currently not viable or picked at all so we are letting this blade dancer bring some magic to the rift by upping her burst ability when building ability power. We're focusing on her high counterplay skillshots in order to give her a distinct playstyle difference compared to AD builds.”

Kassadin

Q Damage increased. E damage increased.

“Kassadin has been a bit stagnant and below where we'd like him to be for resting win-rate, and his pick-rate is similarly declining. We're looking to enhance some of his late game damage output to encourage the high risk/high reward scaling playstyle that his players enjoy.”

Kayn

Q and W mana costs decreased.

“There are a decent number of lane Kayn (Layn) players out there and we'd like to give them a fair shot at winning their games. To do that without buffing Jayn (jungle Kayn), we're buffing mana costs to give him better access to wave clear and scrapping with his lane opponent.”

Kog'Maw

Q damage increased. W damage increased. R damage increased at higher ranks.

“Seasons ago, The Mouth of the Abyss was once a viable and common mid lane poke champion who had a late-game powerhouse identity. He's not too far off from it these days, so we're looking to give him a bit of power to enable it again and get people to try it out without making bot lane shift to AP for trivial wave clear.”

Master Yi

Base Health decreased. Q damage decreased.

“Our fixes for Master Yi Q applying Kraken and Terminus were understandably buffs to Yi. We're looking to reduce his built in on-hit build potency now that the system works in his favor and make his early game more exploitable in order to bring him down to size.”

Miss Fortune

Base AD increased.

“If only there was a word to describe Miss Fortune's current state. Hmm, yeah.. can't really think of one. Anyway, we're buffing her this patch to bring her up to pace with the rest of the pack.”

Morgana

W mana cost decreased at higher ranks. W damage increased at lower ranks.

“Last patch gave us a clean read on how much power each role got from making Morgana's W damage more consistent. With that dust settled, we're here to revisit her with some directly power-positive buffs, giving her better early fighting and making late-laning wave clear less punishing.”

Nilah

Q secondary monster damage increased.

“Nilah will not become a viable jungler with this change but the current restriction around how little splash damage she deals to jungle monsters just isn't needed. We're removing this unneeded mod for now and eventually we may dive into what it would take for Nilah to be functional here.”

Rumble

Passive damage decreased. Q damage decreased at higher ranks.

“Rumble has climbed greatly in win rate since the consistency changes we made last patch, so we're moving some power out of Flamespitter and Junkyard Titan's damage output.”

Senna

Attack Speed Growth increased. Q heal increased.

“Senna is currently underperforming as a bot laner and even more so as a support. We're giving back some of the attack speed growth she's had previously to improve the feel of her attacking builds, and she's getting a small bump in her Q's base healing.”

Sett

E monster damage increased.

“Sett jungle is a lot closer to viable than people realize but still needs a bit of a push to reach true viability. Have fun!”

Singed

Q damage per application decreased.

“Singed underwent several changes last patch that made red side Singed deal his first tick of damage instantly instead of 0.25s late and made blue side Singed refresh his poison much more reliably. The net result of these changes is that in almost all cases, Singed players are dealing substantially more damage in almost all contexts. We're making some under the hood changes to poison duration in order to make the average Poison Trail closer to before, but without the substantial red-blue differences.”

Teemo

Mushrooms (and eggs and other objects) are now more visible.

“We're making a small visual change to make Teemo's traps easier to pick out in the world. They still turn invisible and work mechanically identically before, but now they're just more opaque so you can tell what it is right before it blows up in your face.”

Vayne

W monster damage increased.

“Vayne jungle is a lot closer to viable than people realize but many players completely miss the mark on ability orders. If you want to play Vayne jungle, start with Silver Bolts and then max Tumble. Have fun!”

Yunara

Fixed several bugs that could cause Yunara to deal more or less damage with on-hit effects.

“As players have gotten better at her, Yunara has risen to be one of the most potent ADCs in the game. We've got several bug fixes in this patch that we expect will nerf her popular Kraken Slayer + Hurricane build. We'll continue to keep an eye on her performance metrics to see how she lands after these changes.”
