Have had games where we ace the team but xin and the tank and the xinxou just tanks the turrets and pushes SOLO WITHOUT MINIONS to the end with ease, while a 5 MAN TEAM cannot push at the same pace against a tank. If we send someone to kill him then he just TANKS THE TURRET and dives because of his heal. PLEASE EXPLAIN THIS RIOT. There is supposed to be an element of counterplay against every champion. So far playing against him the only two ways i can find counterplay is to 1 4v1 him then you have his team to worry about, or a champ that takes grevious wounds which is rare now, even then he is still a bitch to kill.
I'm a nasus main and have faced fed xinxou's and his healing is so powerful that I have been fed out my ass with nasus (700 stacks +) and still lost to him, even when he doesn't use bork active.
