I've brought it up before. An adjusted proficiency table would do the game a lot of good. (Only adjusting levels 1-4).

Table
Level 1-4 +3
Level 5-8 +3
Level 9-12 +4
Level 13-16 +5

And as it's been brought up in the past, adjustments to proficiency are a good base for scaling difficulties.

Story: Proficiency +6
Easy: Proficiency +4
Normal: +2
Hard: no bonus
Very Hard: -2
