Cataclysm Hotfixes – Updated Dec. 20

[bluepost]The search radius to find an Archaeology node from the Archaeology ability Survey has been increased. This will result in fewer searches needed while in the “green” range of surveying.[/bluepost]

Update: It seems that they made it so that nodes (fragments) can be discovered at a larger range.  It used to be the would always spawn within looting range.  Now they can be discovered a little farther away meaning fewer repeat green surveys.
