The CAV Brawler is Great!
It's an all round perfect infantry transport vehicle.
It's weapons are clearly designed for defense and pushing objectives alongside infantry. It can not go head to head against tanks unlike the MAV and this is how I believe transport vehicles should be. The defensive grenade launcher is "chef's kiss".
The ability for infantry to still spawn on it despite being full is a fantastic innovation! I hope this feature is transferred to the other transport vehicles, because that sole feature, makes the CAV Brawler amazing to drive, I as the driver don't have to worry about people seat hogging and them preventing teammates from spawning on it.
I also love the fact that its main gun is controlled by a separate player and not the driver, this helps to balance the vehicle out tremendously. I can focus solely on driving and boy, is it fun to drive the CAV Brawler. It handles better than any other vehicle in the game! Probably because of those tires.
I just wish we had this at launch! I'd literally be playing Battlefield Taxi in 2042!
