I had seven pieces of 441 Heroic 5/5 gear before the release Tuesday. On Tuesday I found that two of them are still showing as 441 heroic 5/5 with no upgrade path. One of them is tier, the other is not. The other five pieces now show as 441 Myth 1/3. One of those is tier as well.
One piece is Drape of the Dracthyr Trials, the other is Pants of the Autumn Blaze which is tier that came from the weekly vault.
bug? or some hidden eligibility needed for some gear to upgrade and not others?
Hero gear isn’t supposed to be upgradable to 447.
Only gear created at ilvl 441 or above will be on the myth upgrade track.
When you have gear that shows hero 5/5 then you cant upgrade it. Only when its flat 441 item level and above gear without any other text. that means only late rare hc gear from the last 2 bosses that are 444 i think and +16 weekly vault items.
This is correct. Hero gear that has been maxed out does not convert into myth gear. Only gear that is 441+ from the vault from doing mythic+ at 16 and higher, mythic raid gear and heroic raid gear (anything that drops that has an ilvl of 441, which is generally the very rare drops) will be myth gear and can be upgraded to 447.
