Dunno what I'm doing wrong. General flow of battle

Malgus marauder and assassin starting

About 80% of the time I lose the opening advantage and they hit my engines first

Do only basics on their marauder, don't touch other ships

Depending on if I need the extra debuffs for hangar, I call vader or red trooper, usually call vader if they've already hit my hangars since I still get the debuffs

By now they ai usually calls in SET too early, and I destroy palps shuttle with my hangar sabotage

By now our meters on capitals are pretty even, and thanks to ai and sith assassin I should be ahead because they blow aoe abilities etc. But somehow, wvery time, like clock work, they always get to bridge before i do, and I lose. I can't figure out what I'm doing wrong and its absolutely infuriating, I have all 6* mods on my pilots, all are r7 except for royal guard (I don't have LV so hasn't been a reason to take him passed r3 for the SEE requirement)

Any help is appreciated because I see other, weaker, leviathan fleets pushing me back in ranks but I can't climb passed about rank 15 for shit
