Two remarks...:
- As was mentioned, reputation is mainly needed to get better deals with minor factions, which are the mission-givers at the bulletin board. Increasing reputation with minor factions is way easier than gaining rep with the major factions. It should be easy and just a question of a few fulfilled missions to be 'allied' - especially, when the base reputation is 'friendly' and not 'neutral'. (= doable in a single play-session)
- Maybe, reputation-gain with the major factions could be faster now, reflecting the changes.
...and a question:
- When getting 'allied' with any faction and fulfilling additional missions / continuing whatever pleases them: is there an actual "reputation-cap", which limits tha maximal amount of "reputation points" you can gather, or is it possible to accumulate more and more of those after you reached the 'allied'-status?
Why I am asking this: If it is possible to gain (more or less) unlimited reputation with any faction, there would be quite a it of buffer until your reputation decays to 'friendly'. If, however, the reputation with a faction is capped somehow, further deeds would be in vain and you would lose your 'allied'-status way earlier.
If the later is the case, the rules should probably be changed to the former.
