Guild Wars 2

What if Gw2 auto recorded every match, and at the end, you had the ability to download (to your own computer) or save (to gw2 servers) (former probably more practical) the match such that you could watch it as if in spectator mode and study it. Might be a unique tool that no other e-sport game really has? thoughts?

Gw1 did record matches in game (GvG, and Heroes Ascent) people could view them as spectators from any players perspective. It was fantastic as a learning tool.

Why did they remove it?
