Anyone seen any strategies in rated bgs that you've been tempted to try out?

The last time my team que'd up, we got Twin Peaks, and the other team did something interesting that really caught us off guard.

As usual we divided our team up into a defensive and offensive team, but the enemy team grabbed our flag, and then waited around for a while until our defensive team came into the base. Because they had their whole team there, we lost the flag in no time.

They then proceeded to run down the field while the rest of us were still rezzing and organizing. Our coordination was thrown off for a bit, and they managed to capture two flags using this tactic. After we clued in, we managed to tie with them and get the win, but I feel that if that strategy was better executed, it could be a good one to use.

What strats have you seen so far in the rateds?
