They raise my blood pressure due to all the salt excreted by sweaty AH/LB pilots.
They have their place and can be useful. But on GR, their usefulness is limited. When I use them, I find myself being more stationary due to the need to be a little more thoughtful about using them effectively. Firing close enough but not locking until last min to make the useful.
Limited range on them make them useless against high flying jets, especially those with jdams and laser guided.
On GR, actives are more useful for me. Run and gun. Stick and move. The MAA has wheels on it for a reason.
