I can see how that can speak to some people with a collector personality. For some, that's the point of it all, to have something other people don't. (I mostly just hate the idea of having to spend a lot of money on a card that I want the better art for. Whichever art I like better is the one I'm going to use. If it's the AA version, great. If it's the normal version, I'll use that just fine.)
I never said anything before, because if that's what other collectors want to do, fantastic. But time is running out! People need to make their decisions and if reminding people that if you have a DC tier adding on a Collector tier if you can afford it is a fine choice, since it doesn't put any pressure on you if you want to merge the accounts or not (like adding a RL tier would), if that's enough to tip people over the edge and pick these up before they're gone, then fantastic! If telling people that Cryptozoic said that the AA cards will all be rare and legendaries will help them make their decision, that's important to restate, because it's not anywhere in the tier description.
Being part of an exclusive club can make things exciting, but so can making a last minute decision before the timer is up.
