Currently, destinies gain no benefit from their last rank - after getting to lvl 5 and getting 4 'AP' ranks, there's no point in getting that last rank - no reward for it. It's kinda wrong. 1 more level towards fate points would be cool, while not gamebreaking.
EDIT:
This might be obvious for some, but for me, Level 5+(5 ranks) effectively means Level 6. And, to rephrase my plea, i want 5+(5 ranks) to be treated as Lvl 6 in aspect of fate points - because, as it is now, Level 5+(5 ranks) counts as level 5 in this aspect. This should not be 5+(5 ranks), it should be 6 - it's a matter of simple fractions. 5+(5/5) = 6. make it count as 6.
