A new reward track
won’t likely be anything anytime soon. I would imagine the best option if you don’t like anything else would be the maguuma wastes track—gives everything the other ones do, plus map currencies so you can either hop into chest farms (with bought keys) or trade them in directly for obby shards or gear bags, or whatever you want.
They’re (for whatever reason) very ambivalent about people actually being able to make money from pvp.
