Our goal is to get a new build up on the PTR by the end of the day. This build will bring the intended tuning of the zones much closer to where they should be. We've also fixed a lot of bugs, re-designed some encounters and added some new art (mostly spell effects etc.).
The build going up will also address the Lord Kri server crash that was occurring.
Please keep in mind that we are still tuning and bug fixing. You won't see major design overhauls at this point but we're going to continue to adjust the difficulty of the encounters until we feel like things are close to our intended goals.
