The ArcheAge forum has a new post by community manager "Celestrata" that indicates that the team is actively working to reduce RNG and to increase the drop rates for Archeum. RNG will never leave the game as it is an integral part of what ArcheAge is, according to Celestrata.
Going forward, we want to continue to either remove or mitigate high failure mechanics by adding linear progression systems -- I.E.: There should always be another way to get something. An example of this is the Glider Upgrade system, where you can either buy the item to remove a wingclip or you can just craft it in game. That includes future improvements to regrading, gemming, and others. But, the team here at Trion most certainly agrees with the sentiment of reducing RNG.
