So why are we giving Nocturne an AP ratio again?
Nocturne got a 0.5 AP ratio heal per unit hit with his passive on the PBE. Edit: they released him with a 0.15 AP ratio instead, which, nonetheless, is an AP ratio on a primarily AD assassin/melee carry for the sake of promoting guinsoos. I mean, I understand they're trying to make Nocturne want guinsoos, but he was already a warrior jungler and not a devourer jungler. He doesn't like AP or ON hits as he prefers to hit hard with his autos. For quite a while Nocturne players have been going max cdr with bucketloads of AD and a couple defensive items. Never in any of his strong builds did he focus on on hits or build any AP, or even build devourer for that matter.
So now why are we giving him a 0.5 AP ratio heal per unit hit with his passive? I'm seriously afraid that this will end up becoming an important part of his power budget, and Nocturne will end up having his original playstyles and builds nerfed as a result, despite being at a perfectly balanced place (50% winrate and 4% playrate). The only real issue is that Nocturne only mains only see around a 52%-54% winrate, but this is definitely not the way to fix that.
It actually makes me consider building nashors tooth on him, which is not a good sign. Just a Nashors or a guinsoos alone would give around 40 healing per unit hit, making Nocturne amazing at splitpushing and skirmishes while not keeping his identity as an assassin/melee carry.
Instead of increases build diversity, this change actually serves to limit build diversity in the long run, as either his passive heal will be good enough to go fully hybrid, or it won't be in which case nothing changes. Odds are it will be good enough to warrant at least a gunblade or something.
TL;DR: New AP ratio on Nocturne's passive could kill off standard Nocturne buildpaths and take up a huge portion of his buildpath, leading to a new required and meta build on him in the future, one that acts contrary to his nature as an AD assassin/melee carry.
and maybe a tank item or two if i want to get rid of the frozen mallet. He doesnt do good with on hit.
