overwatch must be too high-level for you if your thinking is still bound by primitive gaming mechanics like ammunition.
Haha, I actually ranked at rank 61 in season 1, when at the time pros were 76+ (the rank system in season 1 was broke, even getting to rank 90 was impossible) so no, its not too high level.
You're telling me classes such as Zarya, Reaper, Junkrat, or many other classes would not be different if ammo was an idiot? I think you're the one thinking primitively here.
Limited ammo wouldn't even change it. People die so frequently that it's only going to really harm better teams. It would also be a severe buff to Reinhardt and D.Va, especially since Reinhardt doesn't even use ammo.
And what exactly do you mean by 'spammy bullstuff'? If you're more of a fan of cover-based shooters, you definitely picked the wrong game. Try going back to Call of Duty.
Wow, such a horribly executed insult. There are plenty of other games that would have made sense to mention with that. Sorry I don't play COD, I'm not that much of a friend.
They wouldn't be overpowered, and if ammo was existent they'd be balanced different than they are while there is infinite ammo.
