Apologies for the late response, we are taking some time off for Christmas.
we’re still not able to replicate this issue, so I’m not sure what’s going. it appears to be ignoring your Axe of Orgrimmar completely, as if the value for it is 0.
we don’t have a character that have Axe of Orgrimmar to test with but testing with other 2 Hand axe it seems to work fine.
Does it happen with any other item?
what happen when you create a brand new Orc Warrior (they come with 2 hand axe) does the weapon say best in slot for tooltip?
