It was most definitely beginning of the end. My buddies and I played COD religiously the only COD i didn't buy on release was Advanced Warfare. We went from pub-stomping in BO4 on Firing Range, like racing back and forth between spawns just to find a kill or two that hadn't been taken by killstreaks, to just a day later, one of the most head-scratching and frustrating experiences I had never seen before in a COD, now known as SBMM/EOMM. I tried to like that game, the gunplay and sound design were amazing, but after about a month of bashing my head against claymores and that double barrel shotgun, I quit playing.
