Ignoring the arguments about heirlooms (which are many).
I have a mix of heirlooms at various upgrade levels (60, 90, 100, and 110; none for 120).
Going into Shadowlands, looking at the beta and PTR, what (if any) are the upgrades? Are they all going to be 1-50 with a 51-60 upgrade? Or do they have various levels (25, 35, etc.)?
Heirlooms scale up to level 49 currently on PTR.
0/4 is up to level 29
1/4 is up to level 34
2/4 is up to level 39
3/4 is up to level 44
4/4 is up to level 49
More special heirlooms that only scale 2/2 start at up to level 29, than jump to level 44 at 1/2 and 49 at 2/2.
Edit: A level 49 heirloom is item level 58.
Edit 2: A Normal Garrosh Heirloom is item level 59, a Heroic one item level 60, and a Mythic one item level 61.
The order should be Weathered → Battle-Hardened → Eternal for Garrosh weapons since they start at a higher level
Tangent: it is interesting they went with a system like this instead of using an item upgrade NPC like we have for honor gear nvm it makes sense now that I think about it. They could do it but it would be weird to drag a loom from the UI to the upgrade window.
yea i tried everything i could, what i did find was that it seems there is a problem witrh not being able to upgrade certain items now including pvp gear and stuff, it seems the problem has been ongoing and blizz hasnt fixed it yet. so thank you very very much for trying to help
