Patch 5.0.4 Soloing Loot Change
We design dungeons primarily as group activities. We have no problem supporting soloing old content as a fun thing to do, but we don't want it be among the best ways to generate gold, which it was at risk of becoming. The metric here is not which methods can earn you the most gold (which are probably still things like being an AH baron or selling raid slots), but which methods were trending as the most popular ways to earn gold. If optional content is too richly rewarding, it ceases to become optional and just becomes the way most players play the game.
You should solo old dungeons or raids to see the content, challenge yourself, or maybe get some transmog gear. We don't think it needs to be richly rewarding, financially. (Blue Tracker / Official Forums)
