Through wrath and cata I did a ton of bgs. I really enjoyed them because minus an op trinket or something everyone was in pvp gear. Since coming back to BFA I didn't do any bgs outside of farming honor for an essence. The main reason was because the gear you can obtain from it just wasn't worth it, and to be competitive you literally must have near bis this xpac. You're forced to raid to get the proper azerite and to get a trinket and in my case bis ring. Then you're forced to do m+ for most of your other items. I only wear like to PVP items, and those I had to wait for like 15 weeks to upgrade an older crappy item with a coin. Outside of playing with my friend of many years/expansions, rewards for pvp in BFA were next to zero.
I was super happy to see vendors returning, and then instantly bummed that at least in its current form they only have 3 iterations of stats which for rogue at least don't include the one I need most haste/vers. I don't expect to be able to have mythic raiding gear as a pvper, but I also don't expect to be farmed by someone just because they have mythic raiding gear. That really is the current state. Unless you're a glad, (which im 2200+) and are just that much better than everyone else, your ceiling is Sooooo much lower with how things currently are.
I would love to see a pvp stat return so that you'd reward people for pvp. Blizzards excuse is that they didn't want people to farm multiple sets of gear.... this is a joke. Currently I have a raiding set, a m+ set, and a pvp set.
The big changes that I'd like to see as someone who mainly does rated arena are as follows:
