Desync in 3v3

[Kaal]

Time and time again I notice that 3v3 has some major desync problems for me. I play as KFM and I've noticed that my skills sometimes are not hitting targets standing directly next to me. For instance, when I launch enemy in air then use stun right before they land. They don't seem to be effected by that at all and can freely roll back or use ground counter. 

 

Moreover, sometimes I have Shin kick available next to a stunned/dazed player but nothing happens when I click it, hell, spam it. While I can move and use other skills freely. This only happens in 3v3. Never experienced that in 1v1 in over 400 matches. I've even checked my networking graph to see if it's lag and didn't see any abnormalities. So I wonder if anyone else is experiencing this?
