Battlefield 4: The MBT LAW Auto Locks

I definitely thing the LAW has some great uses, especially when you have a team of engineers attacking a target, the combined attack can make short work out of a vehicle.
However, I the fact that the Law always comes down on top reduces it's effectiveness when you are fighting a tank and you have no support (which happens more often then not). It takes a lot of shots from the top to stop an MBT (or a lot of other vehicles), giving the tank a lot of time to find and kill you. There have even been times that I have failed to kill a vehicle after successfully hitting it with 3-5 LAW shots.
Therefore, I have found myself using the RPG as of late. The lack of tracking does make it harder to hit a vehicle (though the LAW detection is very small) and you have no laser designated tracking, but the ability to hit a vehicle in weak spots helps a lot. It also allows you to cause mobility impairment if you hit the enemy vehicle right, making subsequent shots easier and reduces the enemy vehicles ability to fight back.
It's hard getting used the locking and then switching to the RPG. But man the extra damage is great!
