Anytime in any game this pops up I just always think to myself.

Everyone funded the development of w/e rewards with them buying the game + subbing, so they should be able to enjoy the stuff made from that money just as equally.

I got a bunch of transmogs in WoW for example you can't get anymore, I'd happily support them bringing those back for everyone else to enjoy, no need to be selfish.

Make it a timed exclusive at best, then let everyone get it after x amount of time using currency that's tied to that activity, just straight up petty to want otherwise, and I don't even care about those ugly ass old pvp rewards myself.
