There are some problems with spectator mode that need to be addressed.
1. It's impossible to follow recons because the camera doesn't recenter when they uncloak. Make it do this.
2. The game should auto-follow the game you're currently in.
3. This should be disabled for GvG or players should be given the ability to vote on whether they want it on or not. Tie means no.
4. The game should show spectators in the party
One thing about the recon problem is that if it recenters then you can always tell your buddy where he is at at that given time. Over all I like the other suggestions except for 4 because then the party just gets spammed with spectators o .e Now if they made a different party just for the spectators then that is a totally different story.
