Hmmm, interesting question, and one that could spark a lot of debate about the best itemization. I am going to caveat my comments by saying a lot depends on your other gear slots and spec. Also, I am just going to speak about i264 items to keep things on a similar playing field.
If you are going to have 4pT10 and not get the crafted legs (though I think this is optimal), I'd advise either losing the T10 gloves or chest.
I think the lock T10 gloves are somewhat weak. You can obtain the
Gunship Captain's Mittens from the lootship battle as a substitute. They have slightly less hit than the T10 gloves, and exchange crit for haste. The spellpower is 10 less, but it has an extra (RED!) gem slot and a +7 sp bonus instead of +5 sp, so that shouldn't be a concern. If you don't need the hit, the 60 frost badge
Gloves of False Gestures keep the crit, add some haste, and again only offer 122 sp but with 2 yellow slots and a +7 sp bonus.
Alternatively, you could opt for not having the T10 chest and instead get the 95 frost badge
Meteor Chaser's Raiment. It loses some crit in favor for haste, has slightly less spellpower than the T10, but makes up for it with an extra blue gem slot and a +9 sp bonus instead of +7 sp.
Just some suggestions.
