As akshan, Akshan doesn’t do too well into ranged matchups and champs with easy to land CC as he will be unable to use his E aggressively.

His Ultimate  can be interrupted pretty easily. You have to be very careful when trying to use it otherwise the enemy will cancel its channel.

Versus poke or champions with a lot of wave clear, it is going to be near impossible for you to roam and help your allies as the enemy will keep you pushed in or take your tower while you’re roaming.
