I'd no issues with it actually..
But since every mission is getting tougher, the slow progress may be a disadvantage to the characters.. IMO..
I'll throw more in if I have any in the future..
- More points after mission completion, maybe? (1st mission awarded with default points, 2nd mission awarded with a +2, 3rd with a +3 and so on...) ((Just a thought))
- Reward skill /Perk/ that is on list or not on list, perhaps? (Just so that the character could cope with the enemies in the missions.)
- Or Mission comes with skill points reward which is = to toughness of mission?
