They are harder to kill then tanks, Do more damage then Libs, and are the faster vehicle in the game. The easiest solution is to cut their health by half. There a Light support vehicle, and if your going to let them do that much damage, then you need to make them a LOT easier to kill. 1 Harasser should not be able to kill an entire Armor column...... Or continually kill anti vehicle maxes shooting it. If you don't want to nurf it, then Max anti vehicle (armor) weapons need to be doubled in damage.
