This man has a point. T3 was so poorly itemized that you would probably be better off in lvl 70 blues and quest drops. This was the expansion, after all, where the first 10 quests in HFP replaced some T2 epics.
That said, this is about skill being more important than gear. It's not saying that gear doesn't matter entirely, and it's not saying that you shouldn't screen your PUGs. What he's saying is that
being "ungeared" is not a valid excuse. If you aren't clearing Ulduar it is because you aren't skilled enough--part of which is experience with the encounters--and it is not because you simply need to gear up more.
Also, a huge part of being skilled is knowing what stats to stack at different tiers of play. Picking the right stats is particularly important when you have a limited item budget.
