Lets discuss Nocturne
Nocturne used to be one of my favorite junglers in league. I've found him for the last 3 seasons as seriously lacking, though. Lets be honest, hes a LOT like Master Yi in playstyle. Dev AS based build, dive into fights and try to kill everything faster than you die. lol
The problem is that with the exception of counterpicking squishy split pushing champs, there legitimately isn't a reason to pick Noc over Yi. Yi does more damage, more mobility, more jungle sustain, and even more teamfight survivability due to Q invulnerability. Nocturne just gets blown up when you enter a fight unless you build tank.
Solution? Well, I think it would be a fun mechanic to have Noc's spellshield (W) contain an AA based cooldown mechanic. This incentivizes building as an AS based assassin, as well as rewarding players for blocking spells. A sort of race against time in teamfights to get your spellshield back up would make him feel much more exciting, as well as bring him in line with other devourer based junglers.
