If there isn’t going to be scaling in PvP anymore, then they need to go back to the old way where unrated PvP gear could scale up w/enough time and effort to a strong ilvl. It’s good for the health of the PvP scene.
Even in BFA you could get heroic raid level gear from unrated and in 8.3 you could grind out your resources for 470 profession gear.
And let unrated PvPers get something from the vault. It gives them something to look forward to with the weekly resets.
