Get rid of honor gear and green wpvp set.
Take whatever item level would have been used for honor gear and scale anything lower up to that item level in PvP scenarios.
Conquest, Epic wpvp, and crafted PvP gear already have systems that work to control the rate of acquisition.
Without the vault rng, everyone will have an equal chance at gear at the same rate. The only decisions you would have to make would be getting some wpvp rewards, saving for a weapon, and what to craft.
Basically the same thing we have now minus vault and without having to spend a day farming a green set you donāt even want.
