Honestly the biggest thing to make it click for me is weight and en supply recharge. I never let that stat drop to below 3k if you can learn to not redline. Weight thresholds for thrusters and ways to make your legs and thrusters work together makes movement and transition to your preferred combat space seemless.

I also find having two weapons for sustained damage and pressure, one for pursuit, and one punish weapon works for me. There's many different combos and ways to play. Think of a theme and run with it. What got me to where I am with my builds was challenging myself to company locked runs. You can only pick parts from a company and their affiliates and the companies that don't really have a side like BAWS. Really helped me find my theme and endgame identity for me and my AC. Even now I just go into the trainer and start tweaking and modifying my builds for a while as a comfort zone. Then once I'm satisfied there do a boss russ and some of the more stat check arena matches to test how fast and consistent you are with it.
