And so your statement which was:
The main flaw of the speed run, it make only one metric matter for success. That metric is damage.
is therefor false, and you agree that teamwork is important.

"Damage" is what PUGs prioritize to support their grand delusion of success. It is not necessarily what they care about, so much as a false measurement for how well they believe they will do. You could say I am splitting hairs or speaking semantics, but there is a difference, and it is important to highlight the distinction between them.

That was my my point.
