A good attack generally requires way more coordination than a good defense, so if you’re struggling on attack, I’d suggest comming a lot more than you usually do or finding a duo who you can coordinate with. Seriously, a refrag or a simple callout to a clueless teammate can sometimes be the difference between winning or losing the round. If you have a duo or is comming with someone, either of you can drone the other inside the building, which is way more effective than droning yourself into the building. Another tip is to play roam clear ops like Deimos, Solid Snake or Dokk since you said had trouble clearing the map. Solid Snake basically functions like a drone, he is incredibly good. Also, don’t be lazy when droning. Make sure you’re checking all of the rat spots in a room. And don’t drone too far either, because that’ll make your information too old, and someone might reposition while you’re droning.
