I have Ryoken...and I still support the blanket bounties.
I think they add to the gameplay for all.
For some reason, certain parties seems to be focusing on the BH bounty board but every house has one.
Even the unlawfuls have them. I should know, I ran a little one for a short while.
It gives the pilot a little something more than just the feeling of winning the fight. It's not about PvP but RP (which I concede to Ryoken that it has been abused - good example sir).
They even get bragging rights (which is possibly why they were abused...).
I think they're a good thing because when you know you're somewhere doing something you shouldn't, expect to get hit. Hard.
Passengers to Crete?
Piracy in House space?
Moving in hostile territory?
These are covered by those bounties and as you shouldn't be doing them and you get caught, expect to get punished.
It's not a free ride.
