For my recent "not-Traveller" game, I decided to do something different in character creation.  Rather than giving characters 4 points in Combat Abilities and 4 points in Careers, I told them to choose 4 Careers at Rank 0 and then divide 8 points among CAs and Careers however they like, so long as they put at least 1 point in each category.  None of the players went the "full scholar" route (7 in Careers / 1 in CA) or "full warrior" (7 in CA / 1 in Careers), but they did appreciate the added flexibility.
