by designing their "guard system" factions DO a lot in terms of faction developement. - not rarely... huge shipyards are added to a guard faction, giving ample justification for the faction to use the largest ships - even if vanilla never supposed to give such ships to such a faction.
of course - maybe such ships would have given to the faction anyway - but maybe not. furthermore - guard systems take the factions idea of RP further some. - they can add entire planets there ( maybe not dockable by players - but that doesn t mean that such planets cannot be RPed as being a vital part of a faction )
for example - there was the idea of adding biodomes to a corsair guard system. - a feature that would change a factions RP extremely. - and that IS power given to factions over RP.
or zoners and their omega-49 gran canaria. - a stigma of the zoners was that they were everywhere - and their only REAL attempt to colonize their own planets was a total and utter failure ( even if it was just an easteregg ).
now they have a planet - and thats something that determines the RP of a faction. its not a guard system - but omega-49 is almost regarded as a zoner guard system. - this is real power - this changes perception of roleplay of an entire faction.
look at recent events.... do you think that a fleet would have assembled if it had been freeport 2 being evacuated? - some zoners wouldn t even know where freeport 2 is.
