Fighters Are Better Assassins Than Assassins
I find it comical that you nerf champions like akali into oblivion while letting Jayce, Wukong, Vi, Riven, Yasuo, Lee sin, and almost any of the other fighters alone. I've played several games with akali and her ultimate needs a buff. Her w should be put where she blinks to or just removed. The people fighting her don't like the blink, the people playing her don't like the blink, why is it still there? And why the hell would I even consider playing assassins when I can do the same thing better, faster, and stronger with the above listed champions. Vi literally only needs warrior and trinforce and she can burst people faster than new akali or half the other assassins for that matter. Wukongs ultimate instantly wins team fights. Jayce gets massive poke on top of his all in being enough to kill someone pre six. Riven gets the mobility of an assassin combined with the utility of a fighter so she can dash into a teamfight with a 1000 point shield, stun 2 or 3 people, and spam q until everyones at half where she can just press r to get a triple. Lee sin has always been like vi, where he needs two damage items and can 100 - 0 anyone that isn't full tank.
TLDR sure assassins were a problem, but why are they the only problem? You just created a meta with a bunch of tanky fighters running around and one shotting people.
also at least buff akali so she's playable. A week or two from now when people have fought her enough they're going to see how easy she is to beat in lane.
needs help, but most Fighters take longer to kill a target than most Assassins.
