"at least in my ranks"...
Bro, I'm gonna level with you. Nothing in this entire game is OP in Bronze or even Silver because we all kinda suck and even Urgot is god-tier if you can play him properly. Sure, some champs do better at stomping sub-30 and Bronze players...but you notice how those champs are almost never played in higher tiers and never in LCS? That's because they typically suck once you know how to play against them.
You remember climbing to 30 and Master Yi was the unholy invincible terror? And how that's totally not even remotely true now? That's because players generally learn to CC and focus him by the time they hit Lv. 30. Fun Fact: this applies to all of the champions giving you trouble...and the same strategy still works so you don't even have to learn anything new. Except for buying wards and pink wards - SERIOUSLY IT'S LIKE USING CHEAT CODES DOWN HERE.
