The ability to recognize and react to threats in a hectic teamfight is part of being a skilled player. If you get distracted or ganked, it's the result of a skill you need to improve (awareness and game sense), not the fault of a "overpowered" champion. It's on you.
There are very, very few stuns that aren't a skillshot or on a delay in this game, and the few that exist are either on long cooldowns, have extremely limited range, or both. If you get stunned, you either failed to avoid a skillshot or you were critically out of position, and doing so opened you up to getting hit with more CC. Be unpredictable, stay in position, and dodge things.
If Urgot is in range to slow you, flip you, and mow you down and you don't have the tools to either win the trade or get out of there, then you are out of position, plain and simple. If you are pushed up without wards to warn you of a gank, then you are out of position. Take ownership of your mistakes and improve rather than blaming the balance team. You can't change Urgots numbers, and they have all the data. What you can change is your positioning, vision control, and decisions in a match/
