my ship is this:
config 1: full lasers on drones(4 lf4 and all other lf3) in speed gens all shileds(my shileds are 288k)
config 2: full speed, full shileds on drones
strategy: config 1 (without seprom, only promerium on shileds) put heart formation, sab until kube is out of shileds, and if ur shileds go down also while u sab, use the skill of shiled, when ur hp are arround 325k, put barrer, when no shiled left on the cube, just shoot x2, if ur shileds drop to 0, let them be in 0, and when hp is in 217k, put diamond formation, use skill, and finnish the cube.
(if u have probs when u are with diamond cos u get out of shileds and shiled skill keeps needing to load, let ur hp down a bit , and lunch pod, after the pod, shiled skill is back and use it, and u are done)
result, i can kill a cube with just 1 of aegis skills(maybe 2) with no seprom, no x4, no rsb, just x2 and sab(eco rockets and credits rockets)
