I’ll agree with the chronic lack of fitting space for missiles being one of the major pain points of the Corax. If you buffer fit you get smacked over the head with requiring an auxiliary power core in the lows and one CPU rig. If you fit for a MASB you get clothes-lined into requiring two ancillary current router rigs and an upgraded co-processor low. At which point the MASB fit loses a damage rig and about 25 dps.
Its ridiculous how tight the fitting space is because of the ship being nearly exclusively balanced for using rockets. You can basically read it as the rocket brawler requires 19 less PG and 43 less CPU for its high slots than a missile fit. At which point you can ditch half the fitting stopgaps and just fit for better tank and damage.
