[Exploit] Infinite combo stun

Since now the combo dmg/effect is not reverted when you cancel it in the middle or so, stun and knockback can be abused to hell and back.
Tested it already and things look like this:
You start stun combo (let's say, stunning punch X) and cancel it before last hit. Effect? Stun is applied and there is no cooldown on skill. Same goes for knockback skills. This gives infinite stun/knockback possibilties. Tested it in PVE and works as described. I was able to stun kill mob.
Of course, in PVP, players will get immunity after being stunned/knockbacked, but group pvp will suffer incredibly from that.
Hot fix needed asap.
