I think it's a good idea with the exception of the person who hasnt seen wanting to watch it and everyone else getting pissed off at him hand having to wait.
I think it's fine the way it is.
I too did my first Raid last night as well. Did the Black Talon Flashpoint. I thought it was amazing. The teamwork, the mission itself. Tons of action, good story to it to keep it going. Cool characters too. Was a lot of fun!
The only way to keep it from happening would be to make sure you never know who hits the space bar.
Blacktalon was awesome.
