I once was fighting someone and they were camped out and I was out of grenades so I used the airstrike. I had never used it before so was quite excited to see the effect. I got into a good position and threw it and then waited. Then he ran away but i still waited to see what would happen. nothing happened.
I think there is a certain time to do it by, thats why it went so wrong for me, but overall it just feels like such a sh*t perk. It should be laser designated with at least a day cool down.
Its like a reeeaaaaally obvious grenade with a long timer. Has anyone actually used it to good effect?
