It’s worth putting a few points into after you’ve raised your most important skills. Persuasion is also used to save you credits throughout the game. I chose a soldier in the beginning which had great survivability, but a very low chance of unlocking story tidbits through conversations. Several guides I’ve read suggest picking a scout character to get a good combination of skills and feats.
