configs are what you like.
I use:
config 1- 16 speed, 6 lf4, 14 bo2 on drones. (sometime I use 4 lf4 and 16 shield if I will be in group fight) also switch 1 gen for a bo2 if surgeon speed is not needed.
config 2 - 16 bo2, 6 bo2 and 14 lf4 on drones (if I am 1v1 with noob sometimes I use 3 bo2 and 17 lf4)
Try to time you sb when you are close to the enemy and save your insta for use after you emp to save damage while you relock. I think the skill is your timing, the only way to develop timing is practice.
start with these base configs and adjust after a few battles. then keep track of the best times to use formations, and techs. I found that a good clock emp and regroup works for most of the players you will fight. Only use all the drone formations when you battle good fighters. Most noobs will use the formations at the wrong times and do a lot of the work for you... :)
