He is just way too strong at the moment. He has everything in his kit. He has the highest mobility in the game, a jump reset, insane close range burst, good long range jump without damage fall-off, a shield (at the size of a truck) which makes him invulnerable unless you're pinpoint on his back, and one of the strongest ults in the game. Every single time I hear that weebstick going off I know we will lose at the very least 2 people. This became even worse with the addition of Ana. Ever tried to deal with an ulting Winston with Ana ult on him? You're dead buddy. I feel like he doesn't really have any counters anymore. The thing is right now that Winston is the deciding factor on who wins the matchup. A Tracer can do everything right to take him down but in the end it all comes down to how well the Winston played. He is countered by beams from Symmetra, Zarya etc but he can just opt out of those fights anyway due to his insane mobility. McCree was supposed to be one of his biggest counters, but I don't feel like that's a thing anymore. You can't flashbang [near] the ground because the shield hitbox is so huge, and then he just bursts you down. The main argument I hear is 'but he is so hard to play' and in all honesty, it shouldn't matter. Widowmaker got no mercy as a result of that argument. So if we're looking for consistency, that shouldn't make him un-nerfable. Besides I feel like his ultimate is the biggest problem. It's way too strong and he has it up way too often. He's the main antagonist to our rock-paper-scissor balance. He just opts out of all fights against his counters because he has decent long range jump anyway. I know he is a fan favorite and he's fun to watch to some people, but it's just heartbreaking and you feel so hopeless when you play against any half decent Winston.
