Tried Warzone, got bored pretty quickly. I feel like there's too little incentive to win, guns are meh, movement feels sluggish, map is too big. Also experienced some horrible lag & stuttering in one evening. I'm actually undewhelmed by Warzone, expected a bit more, especially as I played a few CoD games long before Titanfall & Apex and they quickly became my favorite fps games at the time.
Maybe I'll give it another try sometimes, maybe I'll go on CoD's forums to let all the community there know that I'm going to uninstall their precious BR. :P
