i personally think a Merc shouldn't even be allowed cruisers and BS's, lets face it a merc is in for the money the killing and the rep. each one of these things do not get done in a cruiser and a BS. they both cost to much im pretty sure they would be out drinking, making love, and lining they're own pockets with gold. not saving every tid bit to get a huge ship so they can make even more tid bits.
they should stick to fighters and GB's because lets face it noone is gonna higher a merc from half way accross the system thats in a ship thats gonna take em a hour to get to its location to discover oh the fights done nevermind you don't get payed.
they would have small fast ships to get to they're location fast and do they're job fast so they can get right back onto the next one.
and i personally think a bounty hunter is a man who walks into a place looks at a rather large wall with many posts or in this case probably a interactive console. searches through a database of names of perpitrators and goes out and hunts em down for such and such a reason ie Murder, Attempted Murder, Robbery w/e. get a momento or just plain captures the perp and gets paid by the poster. (in this case a screen shot)
