Here is the thread for feedback on the Val'kyr encounter that was on PTR today.

Remember to note whether you fought the encounter in 10 player or 25 player mode, your relative gear/raiding experience level, etc.

Thanks everyone for the feedback so far :-) For those of you who reposted feedback from other threads, thanks for taking the time to do that. It just helps us so much more if all the feedback is in one place.

Thanks everyone for your feedback, which as you can see is viewed directly by our developers. For those reading who submitted non-English feedback on our other language forums here in the EU, I wish to inform you that we did both translate and submit your feedback to our colleagues across the Atlantic. We greatly appreciate the time you took both to test, but also to relay your feedback. We hope you will again be able to help us, if possible, testing the other new encounters. In light of this, please be sure to check out the upcoming schedule for EU PTR testing here:
