Kled & Sona
Whoa, whoa, WHOA. I was surprised to see no more
nerfs in Patch 6.17 notes. I was a Yasuo, with randuins and my passive shield up, and got hit by 2 Sona Q and died. Granted, this Sona had a lich bane and luden's, but for a support with only 2 AP items, that's quite an accomplishment.
Kled on the other hand, I won't say too much as he is still new. I finally faced a good Kled player, who spent 2 weeks of dedication, but holy shit, he kinda just let his team fly into our team and he 2 shot our Jhin. Dafuq.
