If they could do that, why would they still suck?
You said here:
So you don’t think people suck at WoW on purpose. If they’re capable of looking at the damage meter and recognizing that they’re doing abysmal damage, why are they still doing abysmal damage? Do they suck at WoW on purpose?
Or maybe, the more logical explanation, they’re just not capable of recognizing that they suck at WoW. And that also means they’re not even capable of recognizing that they’re being carried.
