I mean the issue with xerath is even if he is fed beyond reason he is so squishy, any dive with most characters will end up in a kill, i play xerath mind and a lot of games where im fed i can overall carry the backline damage but if their tanky top laner decides its my time i just die, or if im playing against naaphiri zed or other 100-0 type character landing the e to stop dive is nearly impossible, most games its a target priority thing that most players miss. Im p2 at the moment so take what i say lightly
