He is one of the most dangerous laners on the top lane, ganking to try and kill him means feeding him, on hit build gets you killed before you can shred him because well, he does close to true damage from the moment he get his BC, he has more DPS than on hit build which is MEANT TO HAVE GODLY DPS (I had 500 per hit with 1.7X attack speed the previous game) while using very few basic attacks, his gattling deals more alone than any build you can buy, last game the Urgot rushed BC to death dance so he perma regens (by the way he was in W all the time and never OOM without any mana in his build, just nerf his mana at once or make his mana costs like mages so he has to build 1 mana item to spam his gattling like a retard) then he bought frozen mallet and mortal reminder, so he had true damage, close to 3000 hp, perma regen in combat, 30 or 40% CDR, about 800 to 1200 HP shield on a low CD with his CDR on top of that and GA...
Seriously WTF Riot, you give AD champs 3 lethality items, a stat boosting item with a partial revive like zhonya has stasis, an armor melting item with 400 hp, 40 AD AND 20% CDR, you think the game can be in a good state at any moment of that assassin/bruiser meta? Anyone supposed to kill a bruiser is getting destroyed in 2 sec max by a single viable bruiser/juggernaut/assassin while the juggernaut get 800+ shield every 10 seconds or even less in late game with 2000+ base HP and +1200-2000 HP with a bruiser build, with 120-ish armor and 100-ish MR without effort so even an on hit build takes 3+ seconds to melt them without the shield, 4+ with the shield and even more for the likes of Garen who has 75% temporary damage reduction.
You can kite them, oh yeah. Very effective when they are far more tanky and deal more damage than their counters with a slow and something else to stick to their prey. CC them, they will tank, maybe retreat a little while to get their cooldowns and some HP back then come back to destroy more. They often use the destroy rune, having about the same effect as Ziggs' E on turrets, making their ability to push complete bullshit while turrets got pulled down every 10 patches from s5 to s8, making them completely useless most of the time. Nearly everyone can dive except the champions that can't who are mostly out of the meta, see the link? Playing under turret feels useless since a single jungle gank can get you killed 1v2 under your turret that barely hits twice while you get killed with 6+ skills and maybe some basic attacks.
So now, you play an OP champ or you pray. Even monkeys can win lane if the gap between the picks is big enough (typically how Garen players can win even while being bad since on the long run they have more effective HP and damage than most toplaners, pure damage reduction and out of combat regen and no mana cost make him oppressive like his offensive skills do).
