The update for free to play is worse than most of the expansion patches. A lot has changed internally to support free to play. I really can't give an estimation since we have yet another patch on way, but I'm sure something should be out within the next few days. Expect bugs though that will need to be tracked down over the next few weeks.
I deeply apologize for the delay. I am extremely impressed though with the patience the MMOBugs member base has had with this downtime. I would of expected a post or two of abuse by now. Thank you.
