I mean, that just means it's essentially a two-seater. Adding 3rd and 4th crewmember has even less of an impact when they're not even bringing new weapons online but basically just give better tracking and range of motion to the turrets. Which I mean, if you are in a situation where you need to cram 4 people into a ship then that's wonderful flexibility, but you're definitely not flying this fully crewed if you're interested in any sort of efficiency. Especially when I wager those two extra people need extra power investment in the life support, which would mean you need to actually sacrifice some firepower, shield power or movement power.
