It looks like Akali's new kit has put her in a really bad spot for balancing
After the buffs she received this patch, her winrate is still really bad and she's one of the weakest top laners and mid laners in the game. It looks like the only solution Riot is going to come up with to this problem (if they even bother to address it at all) will be number buffs which will eventually make her overpowered because of how high her burst is at which point she'll be gutted again and left in the dumpster.
The problem with her new kit is that there is no middle ground with her numbers. Now that her burst window is so huge if she doesn't kill her target with her first rotation, then that means most of the time they'll either escape or she'll die before she can do her rotation again. This is really bad because if Riot wants her to do well as an Assassin then she's going to need to be able to kill targets and with her current kit the only way she can do that effectively is if she can 100-0 her target with her first rotation which is very bad for balancing.
With her current kit she will never be a reliable Assassin if she can't kill someone with one rotation. Her numbers will always be too high or too low which means she'll either be too strong or complete trash. What was good about Akali's old kit was that her kill window was just in the right spot where if she couldn't kill you with her first rotation she still had a shot at killing you with her second rotation which made her decently reliable as an Assassin, but still good to play against because you still had that window of time to react against her that you don't have against a lot of other Assassins.
Her old kit made it easy to balance her with small number tweaks because her kill window was in about the right spot where it needed to be, but with these changes there really is no kill window that can be balanced around. Against old Akali there was always a good chance she would kill you (which is how it should be because she's an Assassin), but it wasn't guaranteed because of her longer kill window (compared to other Assassins) which made her easier to balance around. New Akali either kills you or she doesn't and that's it. Her current kit makes her too strong if she can reliably kill someone in one rotation and far too weak if she can't. There will never be no middle ground and she'll always be really good or really bad because of the way her new kit works.
I'm assuming Riot will just leave her in the gutter because that's how they've treated her since all the way back in season 3 and will just nerf her if she is ever able to get up to an acceptable winrate. Pretty sad seeing my favorite champion put into a state where she can't be balanced properly. I've seen a ton of of my friends and other long time Akali players just building her Bruiser/Tank now instead of a true glass cannon Assassin which is very saddening. I guess those are just my thoughts for now.
