We know. We’ve spent a week trying to gear up. No need to reiterate what we already know.
But let’s also keep in mind the large difference between last season and this one. We used to go into the next season, geared at Normal/Heroic ilevel. Now, our Normal/Heroic ilevel is only just above Normal dungeon ilevel. Thus why we’re burning ourselves out to try to gear.
But it still doesn’t change the fact that some of us lost our key levels.
There are ceilings of content and currency for a reason. Every ceiling is kept in mind. But they moved one bracket out of keys entirely.
Everyone is different. The disabled person who works as a rocket scientist is not the same as the disabled person who can’t work a job at all. Just as the person without an arm can do KSM, but the person with neurological issues can’t get past a 0 now. Different disabilities affect differently. And that’s fine. There is nothing wrong with people hitting their ceiling and being okay with hitting their ceiling.
It’s not an excuse. It’s simply reality. One some of us are completely fine with, too. We just weren’t prepared to lose our bracket like that.
Honestly, those of us who are giving feedback on where we’re at have been pretty calm and logical about it. The only poo show seems to be coming from those who are beyond our bracket and want to scream and insult. 
You seem to be missing the point. I think I said it in that post? Let me check.
Yep! Just below what you quoted.
