This was a response I got on the forums, which is rather intriguing.
For you, the mbt law might be underpowered, however for the makority of tank drivers, it really is the bane of their existance.
This is due to the fact that after you have unlocked all the tank stuff like we have, your tank pretty much becomes a mobile fortress
We can negate damage from literally anything and keep the tank rolling, the javalins and sraws rewuire the user to be precise and also vulnerable, the rpg 7 is so slow i can have a kid and aend him to highschool by the time it reaches me. And the smaw does less dmg than mbt law and no one uses it.
The MBT LAW is the only real anti-uber tank in the game, it goes through everything that a tank can have: reactive armor? Doesnt matter, active armor? Pft
The crap 25dmg per shot you are seeing right now becomes a very real threat mostly cus we cannot negate it at all.
The LAW is very easy to reload and you do not have to aim much to get a hit, which all results in a superb anti-tank missile
However, it does do horrible dmg to anything else, so dont expect to shoot people with it
