The things you mentioned is barely the tips of the iceberg. You can try and watch all you want but if that's really all you're watching for as indicator of good DPS, you have a lot to learn about each and every single job.
And I'd just ask you how do you know this when you haven't even beaten T5, let alone T8? How do you know everyone who beats it is not min/maxing? As Tiggy pointed out, you're imagining things Yoshi is not saying at all.
And where did they say they didn't expect any group to have enough DPS? They only mentioned intrepid groups that push to turn 9. And I agreed with you that people had to min/max to clear turn 8, please read the person I'm quoting's post.
