I've given Operations multiple tries and I really hate it personally. The general chaos is just too much, which is weird for me to say, since my favorite parts of Conquest is when things are popping off and going crazy. I think it's that I feel like I have no where to hide a lot of the time and there's periods where there's just no down time, it's a constant wave coming at you. In Conquest you can more or less pick and choose what fights you get into, and split off to other less contested objectives on the map whenever you'd like.
I think Operations goes against my general flow of play I've established in Battlefield over the past decade. I can recognize Operations as a great game type, easily the best new Battlefield game type since Rush, but it's just not for me. And I wish it were.
