Rek'Sai is just better a version of Nocturne at this point.
Finally actually played this champion for once.
At this point there is no reason why Nocturne should exist, she has a better clear, she can sense enemy units with her tremor sense. Her CC is a hard CC not a weak CC like Nocts. Her pre-6 ganks are really strong. She's easy to play doesn't require a lot of skill. Build path is wide open if you're really fed you can build all AD like Noct but her E does true damage with fully fury. Her tunnels makes her a monster in split push situations considering your ult gives on the way ping like real lol.
Nocturne is my favorite jungler from season 3 but he feels god awful compared to Rek'Sai.
TDLR; Rework Nocturne because Rek'Sai is just a better version.
and
, which he should have at least one of the 3 late game. Nocturne also has a lot more dueling potential because his fear and bonus damage on Q. Plus, Nocturne has a spell shield. And his ultimate require enemy of an enemy champion in its range, rather than a tunnel. Those are HUGELY different concepts. One is for assassinations or initiates, the other is for flanking, escaping, and getting to objectives.
is a better
as well.
