We just completed character creation for a Rogue Trader game and one of us is going to be the Trader. Now logically he was going to take the Rogue Trader class, upon further examination we cant really figure out what the goal of the class is. It looks like its supposed to be the leader, except the Arch Militant gets better talents for that and gets the other ones faster. To make things worse they dont seem to have skills to be a proper skill monkey.

In short everyone does their schtick better than the Rogue Trader, and while that would be fine, the Rogue Trader isnt a good at being a generalist. So what makes the Rogue Trader worth taking?
