Major gamebreaking Azir bugs
Using any ability or doing ANY form of input be it item or typing with Azir will cause a very short but very high ping spike making any form of initiation or escaping almost impossible. Playing as Azir, even just walking will add delay as if you have +300ms despite having a constant 34ms in my case (250MB/s down 100MB/s Up Fiber) Insec becomes impossible due to these issues as if you send Azir soldiers to 1 spot but move your mouse away from that location the soldiers will be sent to wherever your cursor is at. Same goes for his E and W. Due to these issues Flash + Ult somehow gets reversed, you flash towards the direction you use your Ultimate in, and the ultimate will in return be summoned opposite of the intended direction because of the delay input that always happens when you cast anything.
Example would be if you want to spawn a soldier in place X and send them to place Y, you will summon them at Y and send them towards X. Trying to poke with this leads to you walking into the enemy and spawning the soldiers way behind yourself and not them.
Recreating is a breeze as it is present the moment the game starts until end 100% of the time. You can easily test this by picking Azir and typing something into chat, the text will appear just around 1 second after input at random occasions.
