the best pvp/pve gear
That was the main problem to begin with. They shouldn't have introduce such gears in the first place and keep pvp and pve accesories separately.
They did that because odians and runes were planned. Now imagine changing odians and runes from pvp to pve set or having 2 sets of enchanted runes and odians.
Imo the main problem here is they made endgame pve content gated behind $$$(plat cubes).
