With the way artifacts work ( cannot easily switch between specs) the new longterm relevance of 5 mans, AND the fact that pve players can get a pretty good amt of gear from pvp if they work at it a little, blizzard needs to keep classes better balanced than ever before.
*an example* I dont want to get turned down for mythic+5 5 man, because theres a blood DK available 15 ilvs lower then me, but still much better in 5 mans than any other tank.
My pvp winrate will directly correlate to the gear i'm getting from it.
Do you have confidence that Bliz realizes this, and will work harder on tuning this exp?
