PvP scaling is a thing that has been with us throughout BFA. My personal opinion about it is that its better than Templates but not really optimal. It is too riddled with bugs and certain scenarios will make good items weaker compared to a lower ilvl one, just because of PvP scaling. This is especially true for rings.
I would suggest you all make your own testing with PvP scaling, since it differs a lot depending on pvp item level.
I was not able to go test everything about PvP scaling in this video, since it is quite a large system.
Hopefully there will be some changes to the system in Shadowlands. At the very least make it more apparent what you are actually doing (healing, dmg etc) and not keep it hidden.
