It doesn't really make sense for it to be the second biggest ship in the whole entire game but have a 7 power distributor the Anaconda has a 8 and I believe the type 9 and type 10 or upgrading to A Class 8
Ships have different specs. Just like in real life.
It is also a challenge to juggle with these specs and to try to find the best outfitting with what you are given.
Many for example complained about the Vulture.
It was notorious for its power problems. At the same time many cmdrs felt that this idiosyncrasy gave the Vulture character and they prided themselves in being able to handle this heavy fighter as it was, no matter what.
Of course this was before the engineers.
These days cmdrs have it much easier to overcome system problems by engineering their ships.
I like what the engineers add to the game, but I do some times miss the old days.
