It's probably too late to implement this (maybe next expansion), but I think the purpose of PvP gear should have only been for glamour purposes, while keeping the PvP rank required to unlock it. The purpose of PvP gear in general still remains almost pointless with ilvl syncing. Instead, players could jump into PvP using their PvE gear, and their motivation to PvP (other than for fun and future rankings) would be to obtain the unique glamour gear, titles, more action points for skills, and perhaps more mounts/cosmetics that could be bought with wolf marks. This is somewhat borrowing concepts from WoW's future PvP system, but I feel like it removes the uselessness of PvP gear, and with ilvl syncing being so low, obtaining PvE gear above that ilvl shouldn't be an issue for all players.
