Man you have just been phenomenally lucky with your rolls. Other than your chest and boot, you hit the correct subtats on every one of the other pieces.
All things considered, right now, I'd probably put the weapon, helmet, shield, and boots on Khatun. They aren't really "perfect", but they all have speed rolls, and, if you're lucky, taking them to 12 will have a few of them hit the speed roll. The boots are sub-par - I'd bring them to 12 and leave them there.
The gloves and chest I'd sell right away. They are only 3*, not enough to warrant upgrading.
LOL, thought I was pretty unlucky on top 3 only getting speed once :-) I'll roll those for to +12 and see what I get. Might as well with the artifact event going...
