If anyone on PC wants to practice PvP, there are some training sessions going on in Gauntlgrym. We don't cap any nodes (in a private match) so we can practice 1v1, 2v2, 3v3, etc. It is very active actually. This video has some footage from a session. It also has some great ganking
Directions to join the chat channel and training sessions is in the video!
