I can see your point about BHs. I see plenty of BHs in destroyers - the smallest I think I have ever seen (in Liberty space anyway) was an Orca gunboat. It's a bit OORP as well - people with the money to buy a capital-class ship independent of state assistance (from the house military faction or whatever) wouldn't be taking million-credit bounty contracts anyway.
As far as the house lawfuls go, if you don't want the Liberty Navy (or whatever) stomping on you then don't pirate in Liberty!
No longer active online due to a dwindling amount of non-PvP (trading, pirating, mining, etc.) fun in the new version.
