So I just finished a Flex 4 run and got a 1 Hand off of Garrosh. Now I've been using my Flexible 548 Drakebinder Greatstaff for awhile now and I now have a Flexible 540 Mace of the Old Ones and a Flexible 540 Purehearted Cricket Cage. I don't know whether I should use the Staff or the Main hand and the Off hand.
