Pirating in cruisers not a big deal, since traders were so vulnerable before. This change could force them to do like they need to do. Hire escort, fly in convoys, etc. Since a single bomber could kill any kind of transport, the situation wont change a lot.
In my opinion, this change has nothing more just forcing people to understand the "reality" behind the game. A trader have to pay or fulfill the orders if vulnerable. Thinking about respawning, being mute when has nothing in the cargo hold isnt an option if somebody wanna play on a roleplay server.
