I can see it being annoying, but I think it would be helpful if you are in a game with randoms who don't have mics (which happens a lot these days.) I would definitely want a option to turn it off, and that the useless dialogue (like "good kill") was removed, but I don't see basic callouts hurting that much.
Flag taken, flag stolen, hill taken, hill contested, etc, those are fine, its the other stuff that seemed a bit nauseating.
