.... is too unrealistic to believe that a ships best defense is it's ability to repair it's hull/armor or whatever faster than it is being destroyed. I can see repairs slowing down the ships demise or keeping it above critical levels but currently because of the skill levels of it's crew a ship can stay at full health while being continually assaulted. That just doesn't make sense, if I'm wrong tell me why.
According to Entropedia an RK-20 will do roughly 43.31 heals per second, A kismet will do 108.7 dmg per second.
If you have 2 repairers per section, the kismet will reduce the SI by 22 per second. ( ish) If each section has 25000+si.. this means it will take about 19 minutes before the ship will suffer.
Add in one more repairer, even on an rk5 @ 14.43 heals per second, this time scale is more than doubled. Add in one more on rk-20, the heals out-weigh the dmg.
Every shot on the kismet is costing 40pec.
With some of the bigger crew having way more repair crew on each station at times, the figures become more dismal for an attacking quad.
(ofc presuming quad vs repair crew - not taking into account pilot+gunner team etc interventions)
IMO repair crew are invaluable to the success of a mothership
But as you said, its unrealistic to think that this is a ships best defence. Repair crew are an intergral part of the bigger picture. The ability of the pilot, the strength of the gunner team, the rapid response of the runners, the size of the SI, how well the crew listen to each other and work together, the instructions of the captain and commander - every single thing must be taken into consideration in terms of defence and a succesful offence.
A ships best defence isnt one factor alone - but many of them.
Anyway, the thread has moved on now I see, to more about the gap between quads and MS. Bear in mind this gap was not always there, ( and not there for all still ). MS who are missing key factors like skilled crew or SI will still be a target for hungry pirates, just like it was back in the begining when we were all starting out.
Quads VS MS entices MS to upgrade, it encourags them to build better, stronger defences - this is a good thing for everyone, be it the miners who mine the gold, or the repair crew who get bigger and stronger day after day.
Its the space race
I see your point that you feel its unfair as you have no means of being able to upgrade also, however space is in its infancy, there are still many more middle sized ships to be released between the quads and up to the MS. I think its un-realistic to presume that a MS no1 enemy was intended to be a quad.
