I’m taking a super fast break from updating the incoming PTR patch notes to let you know that that’s exactly what we’re doing; we are intending to launch another patch during this cycle to get a handful of changes back to you to test for the remainder of the PTR.
Bear in mind that doesn’t mean we’ll necessarily be completely done with the patch. We’d like you to continue testing after this patch to root out any more critical bugs and continue to offer feedback. However, major changes will be more unlikely past this second patch, as the larger the changes, the more it puts the build at risk before it hits live servers.
Just the same, we’re still committed to ongoing balance even past the live deployment of 2.6.8. If something continues to perform too well or not well enough, we can (and likely will) continue to revisit both the new sets and other existing sets at a later date. 
Now, back to HTML and proofreading for me.
