Xerath too strong?

Does anyone else not see how busted he is in the laning phase specifically? his damage on all of his abilities is really high even early with high AP scaling, has a brain-dead easy to land slow that makes it so its basically impossible to miss your Q(his only counter play to his abilities is to dodge or for him to miss) and a decent range stun. he can hit me from behind my ranged minions (while being behind his) with an extremely low CD, mana cost, while doing very high damage (my friend plays almost nothing, but xerath and 100-0 tanks with lots of hp and MR every game, even mid/ and sometimes early game) Q ability so there is no playing safe, he doesnt have mana issues as long as he isn't a r%%%%% thanks to passive and the only real counter play is to play an all-in champ like zed, ahri, akali, talon etc.. (I will admit i dont have the mechanical skill and dont want to spend the time to learn and master zed because of his higher skill floor. so he's out of the question for me and most players.) You cant reach him to all-in or even poke because he's always waay behind his ranged minions. and if you do somehow get close enough to use your gap close, and he's not sitting under turret last hitting shit at yours, AND if you play any all-in champ(with the exception of fizz or zed or ahri(who also recently got nerfed)) he can just throw his stun and disengage as basically every all-in champ relies on a dash/gap closer which goes in a straight line(impossible to miss stun). The best part about his disengage is that it also does really high damage and can usually kill you at around 70% hp+ depending on if hes fed. his roaming, thanks to the buff to his ult, involves walking into river brush and ulting a side lane so he can "roam gank" with 0 disadvantages like losing xp or gold from mid.

Before someone says "get good" or "play under tower" or "if he has you under tower then he can be ganked, because he's over extended" or "he's immobile and squishy, dive him under his turret". He can easily kill/poke/force me out of lane while i am under my own tower without even going past the center point between my tower and his(without over extending, and if he does its for like 1 second, and the jungler would have to be by his tower just out of sight to even capitalize). Can easily push and last hit at my tower while its being sieged by minions without over extending. and like i said, the jungler basically has to be waiting by his tower to jump on him the moment he steps the 3 steps out of his tower to siege my tower. Tower diving him relies on having a jungler that can/will dive him which is not a thing 90% of the time in solo Q(im only gold.. i know at higher ELO people actually tower dive.)

In conclusion, a good xerath player has 0 counter play in lane and relies almost completely on him making mistakes rather than your ability to out-play. The beginning of this season with the introduction of tower plates and buffing towers he can be even more oppressive as he can farm and shut you down for significantly longer with the added benefit of towers doing more damage causing his only real counter-play diving him to be that much less enticing/harder to pull off without specific junglers and or mid-laners. Late game he's extremely powerful and fulfills his role well i could say he probably needs to be tuned down a bit specifically with his Q, but i think he is easily manageable and not an issue mid/late game.
