I think Akali should be nerfed
I'm not too sure about shroud gameplay. And watching youtubers play against most likely low ELO people is never a good basis to judge off of. But seeing how easy it is for an Akali to continue dishing out a ton of damage in team fights (under towers / anywhere) as assassins might be too much.
Watching any of the popular youtubers show gameplay where she's under tower and getting a bunch of kills while constantly dropping agro. Although she doesn't have the same amount of healing in her kit, her synergy with gunblade helps make up for it. The amount of pressure she can put down is a bit too high for an assassin if you ask me. Assassins should be about making that one play but Akali's play space lasts for a ridiculously long time. Due to her shroud having a potential of 8s uptime, her low CD Q, and her multiple dashes.
I just think that uptime should be lowered. She steps on the toes of fighter/bruiser champions when it comes to time spent near the enemy. Most assassins get in and get out really fast. Akali can stay near the enemy due to her shroud and pressure for a really long time.
When going against other assassins it's like "oh they used their cooldowns now I have some space to work with, now they can't burst me". When going against fighters it's like "they have more consistent damage but I won't be bursted instantly (well that's how it should be but damage meta...). Akali, however, is like "well I just have to manage her and focus on her for the same amount of time I would a fighter yet also must be worried about being bursted.

is going to be released incredibly weak like
and will be badly in need of buffs to be made viable.
