Now, following community uproar, the studio has agreed to fairly compensate players after all.
“For players who already purchased Item Level 330 Incomparable gear, we have several options available. When the hotfix is released, already-purchased level 330 Incomparable items will be able to be disenchanted with the Flame of Ancalamir to return the full Ash of Gorgoroth cost, plus a number of Shadowed Essence Boxes equal to the number of Essence Slots on the gear. Already-purchased Item Level 330 Incomparable Gear will also have its stats adjusted to be approximately equivalent to the level 330 rare gear available through the High-Enchanter, and the Essence Slots will remain. This allows players to utilize the gear if they choose. Following the hotfix, Incomparable gear will have its correct vendor cost.”
