I know I am in the minority when it comes to liking PvP Supply Crates. My bags were always full of them because I PvP so much. But it gave gold and mats and I always sold all the mats. This allowed me to pay for a WoW Token each month and still have gold left over.
Now I’m super broke, barely any gold. To make up for the lack of supply crates I have been making purple pvp gear and disenchanting it to sell the gems. But now the gems are worth less and less.
I think there should be some sort of way for PvPers to make gold, without having to go out and do PvE stuff. I really did like the supply crates. I know that it annoyed a lot of people, but it worked for me.
the air drops in bfa were great for that reason but i think the op is referring to lootcrate/box/supply/whatever bgs used to have a chance at rewarding. fish. lots of fish.
as some other players in another thread have mentioned these do still drop in bgs from level 50-59. i can only speak to the level 50 rewards and they definitely drop bfa mats.
