That's pretty cool man I haven't even tried spectator mode yet!
As for more moaning about bf4... I think that based on the level you get to play on the beta, "Levelution" is just a complete novelty, gimmick, waste of time that quickly becomes annoying! Right at the start of the game you just get players going straight over there trying to take the tower down. It's just encouraging these idiots to NOT PTFO more than they already do! I bet no one will ever play a public game on this map where the tower doesn't get taken down.. I can see a scenario where one team really is having trouble taking the tower off another, so they take it down. But in reality this doesn't happen. Bases change hands all the time. And even if they were holding it down solid, they would have to have a lot of people there, so you could just go and cap all the other bases while they camp there anyway. Levelution is useless based on what I've seen so far. I'd rather they just put the time in to make the entire environment more destructible than having one stupid building that falls down! Let's hope the other levels actually do some decent with this!
