Well, the chargen I happen to be kicking around in my head would be....
Standard roll, Books allowed core, into the storm, Battlefleet koronus and hostile acquisitions(So yes that means you could use the alt path or alt career ranks, if you meet the requirments). I do ask you inform me what comes form each source. It simply makes it easier for me to not have to guess and book surf to find which option you used.
However, I don't see how to do roll on this site without being logged into a game.As a player I never liked when a Gm asked me to go to yet another site to do x just so I could play on the main site, so I will not be doing that. In that case, I guess I'll allow point buy. If someone knows a site option I overlooked please inform me.
Edit:
Just stick with random rolls, you can roll them yourself or use an online dice roller. Which ever you feel best with.
