AP Junglers.

First of all, i am a huuuuuge fan of AP Assassin's, making plays with zhonya's, dashes and jumps. There is one problem tho, i used to play Diana and Fizz jungle all the time, having fun dealing damage and just making plays, right now, Diana is impossible to jungle with, bc of the new prices of AP items and jungler items, Diana has such weak early ganks, bc she needs the ulti to go in, you have the clear your jungle until you're level 6, but at that moment, you can almost never afford your entire jungle item, Sheen gives no AP anymore so you don't do any damage, which makes getting ahead with ganking even harder, since you can't really kill anything. For Fizz, it's different, but even with his strong early ganks, it's hard to get ahead for some people, i kinda always manage to get 2 or 3 kills early, so i can get some AP, but if you are unlucky or play against a really strong early game champion (for example: Xin Zhao) and get invaded, killed, and get behind, there is no way you can anything with Fizz, Diana and every Runeglaive jungler right now. jungle/melee AP Assassin's should be less item reliant imo.
