but bhg in alpha and gamma makes sense. they are stationed in freeport 10, taus ( alpha ) and freeport 9, theta ( gamma ) to raid those home systems. - its original vanilla and it shows how the BHG works on a large scale.
its playermade that we think that the BHG should not activly hunt pirates but rather only work for single bounties. - but removing BHGs from gamma / alpha would mean removing them from theta/ tau aswell as the only reason they are there is to fight the pirates home systems.
