I totally agree with this, however even if I'd had an MR card for a little over 2 years, which would be the oldest it could be when I found this thread and started, it wouldn't ever get consistent spend. There are a few of us here that don't have the benefit of a P2 and some of us don't have the spend to support other cards while meeting MSR, sometimes it's hard enough to meet the bigger spends. I'm looking at having to MS, if it's even a possibility at my walmarts that I don't want to set foot in, just to meet anything over $3k because I can't do them organically without plastiq to pay my mortgage.
I agree that chase lets us know the rules, but the other thing with chase is I can be under 1/24 and sock drawer more than 1 of their cards and they'll still approve me for another (knock on wood). While amex, even if we knew more about the rules, appears to be quite arbitrary. Sure I've had the card about 2 years and I generally only use it when there are good offers on it and with those I've more than made up for the af.
I just have to accept that I may need to diversify outside of Amex and not get a 2nd hotel card to go with my Hyatt, or get the Marriott and keep it (shudder).
