Per this post on the official forums:

 In making the reality more aligned with the overall goal, Kunark dungeon experience gains have just been boosted on all of the live servers.  They will remain this way throughout the holiday weekend as we see how the new numbers work out.

 Well, it seems that we’ve managed to get a bit of what we’ve been asking for.  I’m glad to see that SOE has listened to the players who were requesting this, as it’s been a bit of a blemish on an otherwise great release.

For my part, I intend on running another group or two through Karnor’s and Chardok tonight to see the difference.  Expect a report sometime this weekend.
