Quite the contrary, i understand exactly what is going on. Your unwillingness to swap gear (and probably to get said gear in the first place) is creating a perceived issue with the AF3 not having many stats that suit your play style. That's fine, each to their own.
I'm just telling you that there are good reasons SE didn't include the stats you would have liked on the AF3. Whether you want to take that on board or not isn't really my problem. They do design gear with swapping it in and out in mind. If you don't want to play the game the way SE designed, and take full advantage of the variety of items available, then of course gear isn't going to meet your expectations. Nothing will ever be good enough if you want to, basically, full time gear.
P.S. Use your Mog Sack/Satchel for drops.
