Originally when the tiers were announced here it was four tiers labeled 1, 2, 3, 4. At some point, this got revised, and was 1a, 1b, 2, 3. I looked again yesterday and now it's 1a, 1b, 1c and 2. Seriously. Exactly who is in which has moved around ever so slightly, but it's still 4 damn tiers. What is the purpose of 1 (and all its subsets) and then 2? To arbitrarily make the people in the last group feel like they got moved up? I don't get it. And it makes it confusing because it means anyone talking about what tier they're in, depending on when they last read about it, might be totally wrong by now. And this is stuff that's only a month old. Watch next week it'll be different again.
