I'm not complaining, as only one of my classes doesn't have the stinger as my secondary, I'm just curious why so few people do it? Often times I've already taken down two air support and a third one comes and I'm out of ammo. I usually have to respawn in order for it to get shot down.
This helps me out with the challenges so I'm more than happy to take out all the enemy air support. I love playing domination where I can get KSRs without even getting a kill. Are people using something else as a secondary that is that much better?
