Why i play Noct top over Noct jungle.
#1 Jungling this season is a horrible experience. #2 Nocturne is a extremely strong top laner, with unlimited sustain, defense from ranged top laners, and the welfare stats to duel ANY melee top laner(besides Renekton). #3 the nature of his kit by default keeps the lane hard shoved onto enemy tower, which allows you to collapse on mid, assist your jungler, and when you hit level 6, you can protect your jungler and mid laner with your R, since youll always be free to do so. #4 probably the best TP bot lane gank potential of any top laner in the game, which is kind of a big deal since bot lane matters so much, especially in solo que.
cons: Tanky diver top laner+tanky diver jungler/or Lee will make you go 0-5 under your tower. Renekton will stomp you. Other than that, there really aren't any.
