There's no way around it: Nasus feels like total shit right now.
I'm not really sure why either. The tank changes shouldn't have impacted him much, but for whatever reason his winrate has plummeted. His winrate is currently at 46.5% and that is accompanied by a playrate of 3.1% (according to op.gg). I am personally struggling with him as well and this is a champion I have been able to get a 60-65% winrate in low diamond with relative ease over the past 3 years and I can't even maintain a 50% winrate with him in mid plat.
His lane phase is shit, that's a given. But his late game isn't even good and his mid game spike seems to have declined as well. I can't put my finger on it but for whatever reason, Nasus is total garbage right now and I'm not even sure how to fix it. It doesn't help that everything is so early game focused right now. Tank items losing HP does hurt too. But this shouldn't lead to such a decrease in winrate. He was sitting at a 53% winrate in the beginning of the season.
Does anyone else have the same experience? I'm not just crazy, stats back up my claims. But I'm wondering if Nasus plyers feel the same because I certainly think he sucks right now unless you max E and win by 15 minutes - and that's a terrible style of play that sucks for both Nasus and his opponent; as if he needed even less interaction.
