This is the most absurd fallacy ever, yet I see it across all game forums, from MOBAs to RTS to FPS.
Win rate means literally nothing. You cannot and must not, ever, adjust balance/redesign around win or loss rates.
A character/faction/unit/weapon in a game can be literally a Godmode hack, killing every single enemy instantly from across the entire map, and it could still have a 50% or 30% or any percent win rate due to player actions.
When something is underpowered or overpowered, it's objectively obvious. It's evident from observation, in an isolated scenario without tactics/player choice/map selection/etc. and without the need for statistics.
The moment you bring win/loss rates into it is the moment you go off the rails and start overnerfing or overbuffing things based on completely arbitrary, temporary state of multiplayer gameplay that depends on random factors and player decisions, not unit/character/weapon performance.
Please, just stop using this flawed argument and try actually reasoning from first principles for once.
tl;dr
its not obvious to boos like you, obviously. I said GCS, the cream of the crop, the best, the elite. And OKW dominated with highest winrate, thats straight up facts and statistics but u still have to try and write a text wall of nonsense just to live in ur laa laa land.
I wonder what you think about UKF and USF then. Maybe they just dont know how to play USF/UKF I guess, makes sense.
