I can't wait to start Kai'Sa spotting!

Think of all the possibilities!

Kai'Sa is closing in on a kill on the enemy Soraka. Soraka flashes the wall and Kai'Sa chases her with her ult, trying to land in front of Soraka. Her ult leaves her in front of Soraka, but also in front of the enemy Malzahar and Kha'Zix who kill her on sight. "Noob team won't follow up"

Your team suspects the enemy is doing Baron. Kai'Sa checks with her W, hits someone, ults in and dies. "WHERES MY FUCKING TEAM!!"

The Kai'Sa who roams like shes Bard, has 40 CS at 20 minutes, and flames her team for "not following up her engages"

The enemy Kog'Maw is low. Kai'Sa tries to flank and kill him. She flashes over a wall into the entire enemy team, Q's 3 people instead of just the Kog'Maw, uses E to try to chase him instead of using the invisibility to escape and dies. Flames her Tahm Kench for not eating her.

Builds full lethality and tries to use E as an escape tool

You're about to solo kill your enemy laner when your Kai'Sa comes flying in with her ult, diving the enemy laner. Kai'Sa dies to the enemy and tower, while your laner dies to your ignite. "Noob mid watches me die and KS gg" and afks.

Kai'Sa tries to 1v1 the enemy Darius, enters melee range, E's when she obviously doesn't have the AS to go invisible and dies. "ADC in 2018"
