I picked up the 251 t10 gloves last night, giving me 4pc t10 (all 251 pieces)
I currently have 245 t9 gloves and legs.
I don't plan on seeing much icc, since I'm an altoholic, so I have no expectations of ever upgrading to 264 t10.
All that said, which is better, 4pc t10, or 2/2 t9/t10? Armory below:
