Nobody is using mic anyway and you can only ping once, or IF you can ping more than once (which i never managed to do), there is probably some delay mechanic built in. This isn't an issue since you are visible on the minimap anyway for enemies close by if you killed someone (except if you kill the person with a takedown melee)
But really.....as far as i observed, ping works only at the first attempt, and after that you just spamming the ping button without any result.
I play with a full squad team death match were all mic'd up just because people dont talk to you dont mean their not mic'd up with their friends
