Loading into a game

If I load in at the beginning of a game and select my load out during the 30 second count down, I can play the first objective. However if I select my load out and then click deploy while the transport truck is on its way to A, I have to wait until A is capped/defended before I can get in. I have to spectate. I have seen others enter the game a minute or two after the game starts and jump into battle. Why can some get in and play while others have to spectate?

I believe that this is a known issue, but I've passed it along to the dev team now.
