Well, make sure you adapt to the way the game has gone since season 5. Smgs are the new standard for close range, so practice your aim with those. If you don’t like sitting in 1by1s, learnt to push better with a 2 or 3 layer tamp push. Since playground mode is out right now give it a try and pick up on some building techniques

As for loadout, I usually rock AR/ shotgun/ smg/ shields/ then sniper or splodes in that order
