I've played quite a bit of Siege, and the french very rarely win. The current system just punishes the defenders for a few people ramboing. It's not uncommon to look at the scoreboard and see that there are 3 or 4 guys on the french team with 16+ deaths. They effectively ruin the game for every person on their team by feeding. If they were limited to five respawns, they wouldn't be able to torpedo every single game they're in. It isn't fair or fun. There is absolutely no way that the team can just 'play together' and make up for such a small fraction of the team ruining thing. If you want to force people to play as a team, perhaps limit the amount of lives they have as individuals, so that each person actually has to think 'Hmm, should I run straight into the enemy by myself 5 times in a row?' It worked just fine in MnB NW, and there was actually a little variation in which side won or lost.
