We always try to design our encounters so that certain classes that have different strengths and weaknesses can really shine. We want to have that opportunity to feel like a hero on this fight or on the next fight and when we're talking about people who are working at , they will find any little thing that can do to optimize the best they can. So when we see things like that, we're like yeah, they're strong on this fight by a little bit so of course we're going to see more of them. And we always do try, towards the back end of the raids to make sure that we're testing enough of those elements of combat and class design that you might try to stack early on but then maybe you're going to hit a roadbump in the fight where you have to take a step back and look at what your composition is again and switch it around and eventually turns into a much more balanced composition.
Without getting specific, I can say that when you complete the Sanctum of Domination raid, you will see a big visible difference in the Shadowlands.
For Valor in particular, I think there will actually be an update next week. The tuning numbers that we have been putting in there, we're continuing to iterate on, although Valor in particular has a little bit lower of a cap that some of these other currencies do, so it won't be possible to stockpile months and months and months of it.
