itachi owns kisame in almost every way. FIrstly, when kisame goes to the dragons to farm, he would use his waterfall, followed by his wave. jus channel ur ulti and its all yours :):):):) ALso, when he uses his images, use the B skill and his images would be gone :):):):) and when its YOUR turn to farm dragons, use the lvl 30 skill, the one that summons the huge creature. then, he can watch helplessly as you attack the dragons. I dont think im a pro in itachi, but these few tips would help you defeat a kisame. However if the kisame is EXTREMELY pro, he would beat you nevertheless. Why? coz kisame is one of the most rigged heroes.
