Instead of looking at the raid as, "This isn't what I wanted," try looking at the raid as, "This is better than nothing."
Sure, the raid is super-hard, and almost none of us have the rosters to beat it quickly. There's also a few bugs, and only 2 tiers, T6 and T7. On the other hand, assuming that the raid will get fine-tuned to a certain degree and the bugs will get squashed, and assuming that the devs are already at work on creating some lower tiers for the raid, at least we have new content to pursue.
Would I rather be doing a T5 raid instead of a T6 raid? Sure. Would I rather do a T6 raid while I wait for the devs to make a T5 raid instead of having nothing? You bet.
