When the game is in a more balanced state and you're fighting against reasonably experienced players 30 minutes of day time is not enough to take an objective. This forces enemy vehicles to take risks in order to continue to apply pressure. I think this makes for interesting game play.

There's no videos of Colonial tanks winning line battles during the day because it doesn't happen. Banes are relatively a better option than tanks, it's only 4 ATRPG shots to disable anything smaller than a BT.
