Your arguments are indeed correct in many ways. But you say those things as if there are no places for BHG players to go when in truth you can go practicly everywhere.
It is actually correct to see Houses finaly forbidding the entry of BHG capital ships into there system (aldo that is not something that is actually being done , even for Rhainland). BH are everywhere and most of the BHG players think they have the authority to do everything they wish. The ID of a BH alows you to go everywhere and do almost everything you see fit. Thats freedom NON of the other factions posses. So , when people try to shut down the entry to SOME of the system you are alowed to go , a war erupts.
Alaska - Liberty generals , admirals use their technology there. There prisons are there and the LSF do their top-secret government projects there. Now , what fleet leader would alow some ex-cons and money seekers to go there ? It is just no possible. No matter the fact that the BHG are at war with the Order. That system is used by Liberty for there top-secret operations. If the Core is to go there , then Liberty should start sharing information about there dealings there , because there is no point in keeping it a secret.
Minor - The Order is the most technologicly advanced faction in the game. Why exactly do you think we can't hide Minor from the Core ? BHG NPC may go there , but capital ships and constant BHG presence just out side the Docking Ring ? When I see three groups of BHG NPC , each one with a Destroyer , fighting Order Anubis NPC's I think that the Order is close to being extinced. But that is not the case , so those pesky BHG NPC are a no no outside Minor. Maby put them in the asteroid field that surrounds the planet , what ever. But it's like every single day , Minor is under siege by BH.
Omicron - 100 - Now thats just rediculas. Our shipyard is there , there is another Osiris there and a base. Thats probly the most heavy guarded and protected guard system. Not only that the rules for entering there have been set perfectly clear by the Bs , but if the space around Toledo is out of reach for the hunters , then how the hell can they know that 100 even exists. Not to mention that I see an armada of BS there. BS's , in our guard system. It's not a matter of "they can go there" , more then it's a matter of "they shouldn't be alowed to go there". Because BH players that enter those systems are fully aware that they can atack everything there and RP supports them. In simple terms , they just go there to PvP and be trigger happy. If thats the case , would you mind me if I parked my BS infront of the Docking Ring of your home planet and killed you. "You BH me iz Order , we arez enemiz" . While I type some sort of RP with those Hunters (cuz I don't realy know what to say to the 100th BH BS I see in 100) , I get atacked with no words of RP spoken.
Every player from every faction can "go" where he wants. It's another story of "if he is supposed to be there".
