What's the campaign situation, and do you run any house rules or adjustments?
I ask because when I see complaints about a player character that requires somewhere around 385XP on mentioned talents alone coming from a GM running a canned low-to-mid level adventure like "Beyond the Rim" that's kinda a red flag to me.
If you did something like allow the players to start at +500XP then that may be your problem. Tossing that amount of XP at a player is a big responsibility, and not everyone is prepared to handle it. I see you've go the F&D Beta in there, so I'm guessing you probably allowed +500 XP because someone told you that the +150XP Knight level wasn't enough to create "Jedi." (...)
If you did give the players a big XP pool to start..then it's kinda your fault. Not only did you hand the player the tools to become Dr. Doom, and authorize that character for play, but you then failed the player by not running a campaign that supported that play level. (...)
No house rule, except the vehicle/ship damage conversion is 5-to-1 instead of 10-to-1 (which we haven't had to use yet). I gave them 150 xp at start, and 20-25 xp every 4 hour "session", and we've had 14 of those. Admittedly a fast progression, but I don't think it's a matter of "too much XP" in this case, since what had caused me problems didn't happen inside the ruleset, but more in terms of expectations and "transplanting" the character concept.
