I wish they would overhaul Fates and take Instant Adventures from Rift. In Rift you could queue into groups in the open world doing dynamic events on the fly. The game would matchmake you with any of the parties with open slots and direct you towards each event. As you chained events you'd get more rewards up to a certain point. Ideally, they would make Fates more rewarding by giving them bicolor gemstones at all level ranges, tomes, gil, etc and let you exchange said gemstones for the same items as hunts.
