Honest question. What's so special about pvp elite gear that it needs to be kept from buying once it's severely outdated? Mythic/heroic gear in pve can be farmed usually 2 expansions after it happens. I don't know why pvp gear should be any different, but I might just not understand. I mean most players don't even know it's elite gear anyway, so it's not like it's being shown off for bragging rights.
