Riot didn’t even buff nasus in the “correct” spot anyways. He can still get beaten up hard early and he is still very kiteable.
If anything I think you should work on how to kite him in this current state. Ask your teammates to CC him for you, ask your support to go something like leona in champ select or even tahm.
Just a couple of suggestions, but the main thing is to adapt and find a strategy that works for you.
And btw this is from a nasus main who has played nasus after this buff, everything that I said about his weaknesses are true, don’t deny his weaknesses just because he can sometimes get onto you.
And btw he is a juggernaut, which the definition of a juggernaut is literally the champ that kills the fuck out of you if you get in melee range of it.
I’m not hating you or anything, I wish the best of luck to you in your future games against a nasus.
and I know what it feels like to get one shot or two shot by nasus when you are a squishy champ, I know the pain too lol
