I have recently been doing a lot of spectating of ZaphodX's 1v1 practice games and I have noticed a few annoying things. There is no private chat for spectators, so it gets annoying when we want to talk between spectators and cannot. I would also like to ask for MORE SPECTATOR SLOTS. It gets really irritating when you want to observe and you have to be one of the first 2 to click. And the last request is pings for spectators, basically a simple fix for this is to make spectators their own team, and allow pings but not anything else.
So spectator chat is definitely going in (and ping eventually). As for the spectator limit, we are mainly concerned with bandwidth (spectators consume the maximum amount of bandwidth). We will probably increase the limit latter on. Until then you can always just delete your commander to spectate a game.
And ruin the spawns for the players. I've only ever needed 3 - even increasing it by one would be fantastic.
