Patch?

They're playing on 4.14; looks like either he's still straight up god-tier in competitive, or they just haven't found/practiced anything good enough against him yet. Nasus worked pretty well earlier today, Dig vs TSM, but they lane-swapped, so we can't know for sure.

He's still very strong, they just reduced the length he can channel his Ult, but it's still on such a low Cooldown it's up all the time. Being able to give other players on your team 20% DR is still very effective, even if limited to 10seconds rather than how much mana you have.
