Pre legion Legendaries

so random thought I’ve had that I haven’t been able to find a direct answer to(or maybe I just missed it in some of the tangential posts I did find) what happens with the pre Legion legendary weapons. is Shadowmourne, the warglaives of Azzinoth, and the others just going to no longer be equippable or will they become “current” strength weapons? while I hope they will become current strength. I suspect they will be either fully disabled or leveled down so they’re not useful in the new content areas

Makes you wonder about all end game expansions raids, if all things are being adjusted to fit the 10-50 model. What would happen if we farmed the heck out of those raids now? If i had a full set from ICC would it be BIS for fresh off the boat 120 Alts? Might be a good way to ensure all alts have decent gear that are not raiding.

On the legendary front,

Being able to start Shadowlands with my staff on my Shaman would be awesome.
