The dragons are respawning almost instantly after they are killed. Guilds are sucking up ludicrous amounts of epics from this, and I bet on servers where certain factions completely control the server, are completely one-sided or even “one-guilded” benefits.
I hate to suggest this because typically it would seem like a last resort type thing, but we need a roll back to the dragon drop. This is actually a very serious screw up and it needs to be immediately rectified somehow or we are going to weather probably what is the biggest loot exploit this game has ever suffered, that not everybody even has the ability to take advantage of, given the nature of world bosses.
