Inconsistent Vehicle Spawns

There are certain maps, where only 1 team has an attack heli, transport heli, or tanks.

Iberian Offensive

Manhatten Bridge

Sobek

Probably others. This makes the game borderline unplayable, and extremely unbalanced. I've posted this, because after 5 days, there has been nothing said about it. yet you have just increased out of bounds timer on one of the maps today?!
