Nocturne will need an eventual rework, right?
He gets too much free stats from his abilities (bonus AD from Q, bonus AS from W), his approach is very binary, and he's not very survivable for an assassin/dive fighter. Plus his background is totally obsolete, so he seems like a prime candidate for an eventual VGU.
I'm not saying his whole kit should be reworked (his ultimate is still awesome), but there's plenty in his kit that could be done better.
