Safe zones should be marked on map (and updated for each cap point)

Agreed.

However it sucks that teams are forced to fight over just one set of territories at a time. Battlefield had this mechanic right. Just leave all capture points open to capture by any team at all times. Makes for some good fun when you manage to get past the enemy's main force, capture the point behind them, then let your team spawn there and get the enemies in the butt.
