yeah it must have been silent in an update, meaning they were too afraid to mention it, thinking no one would figure it out. Well I don't use the harrier too often but the last time I did it got me a few kills.
I think a HUGE part of it is that more and more people are using cold-blooded, because when Ive used the predator and everyone enemy is supposedly spawned(I make sure before I call in) I only see like one enemy on the map so this is probly it. As EVERYONE got sick of air support, and the counter to that is cold blooded.
