There's no disagreement, as the point of my post was that it has no legs after the de-val. I find the alternative non-AMEX 0.8% option good if appropriately assigned to the correct card, but given I don't have the specific single AMEX card that makes this option at the higher cost as profitable as a 1ppd non-AMEX at 0.8%, and as it is only until the de-val in April, not sure how much of a winner it is overall. Each to their own.
For reference (as I am sure I'll be asked) I am using the ANZ 1ppd until $7.5k per month (splitting payments on purpose) and then the balance on dragon at 0.85ppd after birthday bonus.
Edit: Plus, it's 0.8% after 1K per month so whilst a long-winded calculation and having lost the information above to compare it to, I don't think you're really walking away with many more points than me, and I'm not even optimizing it as much as I potentially could using non-AMEX cards, I'm just using what I have.
