This is what I see:
 * Passive: a temporal cooldown bypasser & an AA-self-sustain.
 * Q: Delayed conic damage dealer.
 * W: Tank shredder or brief hard-CC.
 * E: Basically a passive add-on for energy restoration. Dash with.
 * R: MS & resistance buffs. 800-range  ult AA-enhancer.

As I mentionnd above, from the way you describe the combo-ability of the passive, the passive simply bypasses cooldowns in some situations. Regardless if an ability is back on its 10-second cooldown, as long as Nerante has energy and a normal ability off-cooldown, he can recast other abilities as their enhanced version (bar for W, are stronger).

Thus, it's not about being split being between different roles, but he does well in so many areas. Many of the others have pointed out above, but the kit supplies too much in given departments. Flexibility is nice, but when it's offered in the sense that hack-and-slash games do it, it's not suited to LoL. You say he's a fighter, but he has more than enough damage to be an assassin too. When transitioning a character from another game, as I've mentioend before, learn to adapt them to LoL than staying grounded in the fantasy they fulfill in the previous games. Not every custom champion can adapt their counterpart and you might need to learn those bounds when you are receiving this much criticism. I haven't seen you write beyond clarifications any words of "oh, let me try changing it to your suggestion" or "I was wrong there. Does this make it more feasible?"
