Some major changes are coming to the way Guild Wars 2’s loot drops function for level-80 characters, which the devs hope “will provide both quality of life improvements and help with the long-term health of the economy.” Starting on March 26th, “Core Tyria and Heart of Maguuma regions will now drop Unidentified Gear rather than individual fine, masterwork, and rare items,” and the magic find stat “will no longer affect the results of identifying Unidentified Gear.”
To summarize, the devs say that players who have “been playing in areas that [already] dropped Unidentified Gear” will have their chances to receive exotic gear and legendary precursors slightly decreased, whereas players who have been playing “in core Tyria or Heart of Thorns maps” will have their chances for exotic gear and legendary precursors slightly increased, which “equalizes [players’] chances of getting those drops across any part of Tyria [they] like to play in.”
