Look what I got!! This is 🔥🔥🔥 Happy birthday for from me to me ))) I dunno if this will work out the same way for elite 2 controller but this is how how I had my elite 1 setup for BF5.
Paddles mapping - top left = A, bottom left =X, top right = LB, bottom right = RS. My triggers were sitting at 30:50 for a full trigger pull.
I'm super excited to try out elite 2 sticks sensitivity adjustment options, I've heard a lot of positive things about them. On my elite 1 I had them on Smooth. And to save the battery I always lower the vibration and the Home button brightness.
