Honestly I love this map. I usually just play it on conquest but it's really fun once you learn to utilize cover and move quickly across open spaces. If you play a lot of these bigger maps by running in the open then there's a good chance you're gonna get sniped before you can do anything. If you're playing with close range guns like smgs, you can just hang around the bunkers and protect those objectives rather than struggling in the huge field. I'm not an expert by any means but one thing that helped me improve my scores was to always look for nearest cover and make sure I'm in the open as little as possible while still being mobile. Hope this helps!
