There is legit 0 counterplay to nasus right now.

you can't say that "stopping him from farming" is counterplay, because you can't stop people from farming forever, and even then at lvl 6 he has one of the strongest engages ever. you can't think that giving the guy that farms all game to stack damage on q and builds flat tank with a glory has counterplay when his infinite damage stacking q has a 1-second cooldown in the form that gives him armor and mr over time with a hp boost, and basically a 6 second root and armor reduction aoe. like dude, no one can fight him right now, and before I was fine with nasus, he was only bad when against lane bullies like Darius and renek and teemo, but now we're at the point where at lvl 6 he has no counter.

• Teemo blind 2.5 seconds nasus q has a 2-second cd in r with ~10% cdr, therefore making teemo's blind irrelivant, and you may say teemo can get away if he just runs thu his mushrooms, well thanks to that permaslow/atk speed reduction. he cants run regardless, and can't prevent nasus from just pressing the q key 4 times to kill him.
• renekton only receives healing from q and CAN burst nasus, but if nasus just backs to buy armor and a sheen renekton can no longer burst him and is left with someone who lane bullies him, which is complete bullshit considering he's a very strong lane bully with insane burst, but when nasus can just slow him r and q spam and proc storm raiders leaving renekton looking like he was just shot in the knees and getting smacked in the face by an MLB player at full force.
• Darius can slow him and can do immense damage in an extended fight to kill him, but yet again once Nasus gets a sheen or just ninja tabi's he can just wither and charge onto darius procking storm raiders and making it completely impossible for darius to continue.

nasus already did very good damage at 100 stacks in a sustained fight, that leaves him with around 200-300 damage per q without sheen prock but with 50% cdr on pressing r, he can do this way to fast for counterplay this buff was a terrible idea and i it should be greatly nerfed or removed entirely for some other passive effect.
