The aim of this game’s balance is not to create a diverse tournament meta that caters to less than 1% of the player base. Because it’s simply stupid. These players are so good they make almost no mistakes, therefore even the slightest adjustment in power level can change the meta.
Bastion for example is fantastic in lower leagues, despite being a severely underpowered hero. Brigitte is also completely dominating lower leagues despite being on the decline on the high level meta.
So he’s being picked more than 2 other tanks that would strongly suggest he’s more meta than them. Just because he’s not the go-to meta pick doesn’t mean he’s not viable. You need to seriously try and think about the message you want to send here: Are you asking for Roadhog to be viable, or are you asking for Roadhog to replace Reinhardt?
Win rates are really difficult to go by, because the statistics you’re quoting include everything such as games where he’s not played with a favorable composition. Let’s say Hero A has a win rate of 55% on average, but doesn’t offer anything unique to any composition. Now let’s say Hero B has a win rate of 45% on average, but jumps to 60% when played together with Hero C.
Do we buff Hero B to be equal in average win rate with hero A or do we allow the designers to create heroes that require more strategy and divert from simply playing a standard Reinhardt composition?
Which brings us to the next point,
You’re just quoting statistics but you’re not actually using them as an argument. Because right before you said it was a problem that Roadhog was slightly below the average win rate, and here he’s above.
“But it’s lower than the other tanks–” But the game isn’t designed purely around roles as a whole. You’re not limited to a certain number of tanks. And a positive win rate at higher leagues, much like Widowmaker, suggests that if you know what you’re doing, you can win with Roadhog.
On another topic I’ve suggested what Roadhog needs isn’t just tweaks or buffs but likely a smaller rework. His kit suffers from what’s called the “feast or famine” type of design. Either he hooks people in and instantly kills them and he’s great or his hooks are constantly blocked by shields and he can’t do anything. There’s almost no in-between.
