Guess you were not there last night when Harvester08 and Guard00 both in cruisers were destroyed.
And the reason that Omega-15 is patrolled in ships larger then gunboats is due the the fact that we have not seen any Harvesters in anything less then cruisers.
using the zoner ID is always possible. zoners are those that chose exile ( but not the hardcore exile as an hermit ) - the ID allows you to use the ships you have and you d prolly be embraced in the community...
... of course there is a huge *BUT* upcoming:
what zoners do not like is upcoming trouble that they cannot steer. - so if you re facing immanent attacks from a house, it might be trouble. - however, the only ones that attack you out in the omicrons is the LSF anyway, cause the military won t dare to fly an expedition into pirate space.
you d have to become zoners then - when you have a zoner ID. that means... no more military operations that are not fully in the interest of zoners. furthermore, the presence of a warship fleet might attract suspicioun among those that consider the zoners neutral. zoner warships are meant to be around, but rarely seen .... for a good reason. they are not parading around with them.
so when you became zoners, you d have to lay down a bit, let time pass and become "invisible". - i don t see the order having a problem with an ex navy group - and the gmg won t make problems either there.
you could settle down in one of the less used freeports - like freeport 10. i d recommend to settle down in the rim systems instead of bering, kepler or other corewards systems, cause there - it would be likely to have a navy expedition to "bring you back to liberty .... as a whole or in pieces".
another option is indeed the BHG. - the guild takes them all - if they have their own ships its even better. - but the community was very much against it ( remember the voices that said "no exceptions" when it came to non BHG equipment and ships ) - yours would be an exception that i could live with - but i daresay, you d get quite some flaming for it.
the guild would prolly deploy such a battlegroup in the omicrons as part of the core. - stands to reason... you ll be even more "Killed-on-sight" when you have BHG IDs and tags:D
