Ah, I had misunderstood and assumed it was on a RTW ticket (DONEx or DGLOB34) since this is the oneworld RTW thread. If it's a standard AA ticket then best asked in the AA forum. RTW are unique products that differ in many ways (including mileage earning in some cases) from regular tickets.

But just for the heck of it I did a calculation, I'm not sure what your fare class is, but RTW tickets book into D class. It has a 150% cabin bonus on QR codes plus your 80% PPro bonus on the base miles, so on a QR D fare you'd earn a total of nearly 66,000 miles / LPs on a DFW-DOH-MLE round trip. To get to that level on AA codes (8x revenue for a PPro) would require a bit over a $8k base fare + airline surcharges (not taxes and airport fees). But if you're on an I, R, or P fare then that significantly lowers the bar of the break even threshold since the cabin bonus isn't nearly as high and could easily be better on a revenue base on those fare codes.
