Based on the initial post time you may have missed the stream. You will totally get one add before you get on It is another tool to better your skills to see something from a different perspective. Also what you see if all your doing is watching is interesting. By that i mean if you take the control aspect out and only watch its a different ball game.
This is very true. But if your brawling with and watching at the same time, you can see where you made a mistake 3-6 secs after your PK or lost a wing. This gives you really fast feed back. only other way to get this info is to save your film and use the viewer.
The feed does not help you as the delay means the fight has moved on by that time.
I watch other streams and podcasts while flying as it helps shorten flights to and from combat.
