In domination I don't understand why capping C is necessary. Now I'll give the scenario that I'm talking about.
Me and my team have A and B locked down secure and the enemy isn't spawning all over the place they're starting from the C flag. We've got everything cool and locked and the game is going well.
However one person then decides to go and cap C, we have a decent lead and we know that unless they somehow dominate us, they won't easily catch up.
Now when they cap C all this does is make them spawn near A or sometimes B but B areas tend to be somewhat 'cold' spawns and then they cap A and we cap C and then the process is still the same, but some minor disruption has been caused.
So what is the logic behind this?
I'm not new to dom but I've always wondered about this.
