EW’s Relics?

[SieyaM]

There is no really hard precedent. HW relics were added in 3.15, SB in 4.25 and ShB in 5.35.

Regardless though, the relic will always stay worse than current savage weapon until the very last patch of the expansion.

True, but you only need that if you plan on doing more Savage or ultimates, which if you don't then there is no reason to bother with it unless you're pursuing glam.
