He's really good in 1v1s, but he needs items to do so. He has a weak early game, as he has almost no laning pressure unless he all ins, and, even then he's beaten by a lot of champs. The meta is early-game based; Noc is bad in top lane vs the current meta @ top.
Jglin, I don't have problem with his clearing. A lot of champs just outperform him right now. He's a diver/sustained fighter, and he's similar to
. All those champs are just being outperformed. Need diving? Tanks do it way better. A lot of hypermobile champs can pull it off too. The divers don't have much mobility, other than their 1 diving ability. After they go in, they can't go out, and they can be kited easily. What is Nocturne's forte? His splitting is average, his dueling is good(but once again, item reliant(
)), his diving is outperformed, his clear speed isn't incredible, and, he can't even go for a full dueling build, as he has to go tanky to survive due to being a diver. His kit isn't super focused for dueling either, which is one of the reasons why he NEEDS items to duel well(unlike
who have innate dueling-based abilities, so they are better off than Noc)
