The luck will remain unchanged on the TBL Chase loot. Therefore; the shoulders and ring will get upgraded for DPS classes by (Tier 2) group gear. The Tier 1 gear has no luck on it at all(But is attunable, and non-prestige I guess you have to pay a subscription for the luck stat) Anyways, just thought I'd give those not in the beta forum a heads up. So if anyone was wasting their time still leveling either the ring or the shoulders; you can stop now. It's just a waste of time.
