Thanks guys for all the feedback here as I've been tracking this thread for quite a while. With Battle for Azeroth we aren't ready to share information on what changes may be coming past what has been shared at BlizzCon.
PVP is something that has been actively discussed going forward into the new expansion, no idea on if any changes are going to be made but keep in mind we still have a whole testing cycle to go through so please keep the discussion up.
