[Gameplay 6.22] Courage of Colossus on Tahm Kench

The new mastery that is supposed to trigger a shield when landing a Hard CC on an enemy champions, but it doesn't seems working.

Hard CC : Airborne Forced Action Silence Stun Suppression Suspension

I know that Tahm's Q is a Slow, that this isn't qualified as Hard CC, but Q with 3 stacks is hardly a Stun, so Hard CC and should proc the shield from Colossus. Same goes for his W, his Eat-a-mother-fucking-champion, should trigger the shield too. With 3 stacks, it should be considered a "Forced Action / Suppression", but it doesn't proc the shield too.

Seems that, going Courage of Colossus on Tahm Kench is useless, due to in-game bugs. I guess that the cause is that Tahm's Q and W are conditionnal to his passive, needing 3 stacks to become Hard CC as requested. Until a patch on this, Tahm is going to be obligated to go Bond of Stone or Grasp of the Undying, since they deleted Strengh of the Ages...
