I’d like to suggest some sort of tutorial mode for PvP. It was present in Guild Wars 1, why did you not include PvP tutorials in Guild Wars 2?
Also the NPC enemies you can fight at Fallen Halls of Glory at the Heart of the Mists lobby map is a misleading indicator if you’re ready or not. Enemies found at Forest of Aarden are a much better indicator if you are ready. With this, I’d like to suggest tougher versions of enemy job class NPCs that you can fight in another area, maybe an NPC with a build that a dev would actually use.
