Just played against an AP Xin
We barely won and I mean barely. Was a 100 hp nexus defense and then rush down their nexus kind of win.
He jungled, got sated. Was healing for about 500 every two autos with 2.5 attack speed.
He surprisingly was able to burst down our carries pretty quick as well.
I was the Noct.
