This game needs a lot of balancing before PVP, I played a few matches of PVP when I first started on the game and found in unbalanced and quite boring and I do play PVP on other games. So I think this bootcamp is them trying to breathe life into a dead fire and a waste of time.
No offense, but a "few" matches don't give you an accurate picture of the game at all.
Losing is a part of life in any PvP game. You can't possibly expect to be as good as people that have been PvPing for the life of the game in a short amount of time.
