Cooldown for C4 spam.

For some reason assaults can toss out C4 as fast as they can throw. This means they can take any vehicle out in an instant. They can also then resupply themselves with more C4.

This means they can take out vehicles more efficiently than engineers. There is nothing like this for the engineer class. Its weird that the assault class has the most efficient and fastest way to destroy vehicles.

RPG was nerfed with a timer. So now the assault can take out vehicles faster than an engineer. Assaults as a class should not be better equipped to take out tanks than the engineers.

Assaults should have similar time delay between the C4 sticks that they can throw out. So taking out vehicles would take a similar time.

Even if engineer moves close to a vehicle, there is no instant way to take out vehicles for the class.

Even the mines have a time delay, if you drop a mine it takes some undisclosed time for it to actually start working. Mines also do not work if you throw them onto the vehicle, they will just fall down and do not explode.
