CC fucks Akali, no matter if she's tank or not. And if she shrouds, there's a nice little ward upgrade you can buy. It's called
. Not only will it show her, but it shows her in a cool way too. If you don't want to buy it or the support doesn't/refuses to then there's another option.
! Still refusing to buy pink wards? Your own fault unless you're full build.
Also, when she shrouds, depending on who's on your team there may be someone or a few people with a skill(s) that cover the whole area of her shroud or a good portion of it, who can MOVE HER and cause her to be seen or just do something to show/hit her. Those champions are:

Now, shall I explain? Anivia: Q and ult. Annie: W and if she's willing to risk, Tibbers. Brand: W. Cass: Q and W. Cho: Q. Corki: Q. Draven: E. Ekko: Q. Galio: Q and E. Gangplank: Barrels. Gragas: Q, E if willing to risk it, and ult. Graves: Q and W. Janna: Q. Jayce: Cannon Stance E+Q or just Q. Jhin: E. May not be that large, but if she steps on she's slowed and shown. Karma: Ult + Q. Kog: E and ult. Lee Sin: E. Lucian: W. Lux: E. Malz: W. MF: E. Morgana: W. Nami: Q and if willing to risk ult. Nasus: E. Nocturne: Q. Orianna: Q+W. Rumble: Q and ult if willing. Sion: Q, E. Sivir: Q. Soraka: Q, E. Swain: W. Syndra: Q+E or just E. Talon: Q. Trundle: E. TF: ult. Twitch: E. Urgot: E. Veigar: E+W. Vel: Q, W, E. Viktor: W. Xerath: W. Ziggs: W, E. Zyra: Q, ult.
That's a LOT of counter play I'm seeing JUST for her shroud. Let us not forget Leona for full on "screw you stay stunned".
