I noticed that Hurok's 4th skill does not stack anymore. I tried him in a Duell with a Guildmate against Kong several times. He devours the illusions, but the haste buff only appers once over his head.
Moreover one can see that he doesn't get 4 times 20% haste, attack and so forth.
Please do not stress his ultimate, I would no hard feelings if that would be fixed, either in translation or mechanic.
But his fourth skill is the illusion counter and it did work as described.
Why was it touched?
