Xerath
AS good as a champion as he is, his ult needs to be changed i feel, besides how its glitching when its activated so u only have 2 shots instead of 3, they have made it to easy to dodge xerath's ult pot shots, so instead of 3 shots that are glitched, it should only be 2 but make the 2 shots splash area bigger so they are more likely to hit the enemy.
On a side note i know its the new tank meta but it feels like ap damage ratio's on every ap champ was tweaked, cause no matter what ap champion i play my skill shots are hardly even fazing most of the enemys i hit, well the ad ratio is still overly tuned up letting ad melee champs just shred ap champions with 3 hits, well in turn i could hit those ad people like 6-7 times and it would barely get them to 50% health and i would be oom after it. so i think the ap ratios in turn need to be balanced more early game and lessened from the late game glass cannon
