Possible Tahm Kench bug in LCS game?
EDIT: Sorry, I meant Fiora bug, not Tahm Kench.

At that time, Tahm Kench shoots his Q at Fiora, but it hits her W and when she blocks back the damage, Tahm Kench didn't get stunned, but slowed instead.
As I remembered correctly, if the damage includes a CC, her parry would stun instead of slow.
Is this a bug? Or am I missing something here?
