I dunno man I think there's a bunch of bad Hog players. Most Roadhog duels are hilariously easy for me as they don't know how to optimise the combo or do a right click head shot before hooking primary fire then melee, side step primary fire again.
I mean definitely Dva's E destroys all your damage and ultimate output, which is why Reaper is useless if you have a half decent Dva play on your team.
I guess it becomes a skill matchup which is better than a hard counter situation, with reliance upon the rest of your team.
I get so confused when I hook one of the opponent tanks and no on my team tries to assist and shoot the person being hooked, even if I call it.
