I got 2 set of T14, a ilvl 496 Glove and a LFR 483 leg (1004 Agility, 1626 Stamina, socket with Hit 509 and Haste 471) for the 2 set bonus.
Should I change the legging to ilvl 496 (1063 Agility, 1835 Stamina, 2 sockets with Hit 393 and mastery 783)
I use shadowcraft and 2 set of bonus give me higher dps.
