widowmaker666: I beleive on level up (I noticed at lower levels it did this) your stamina should go back to full(all levels).
I also think the amount of skill points earned per level should be gaged on a sliding scale it could be descending ( level 1, 5 skill points, level 10, 4 skill points, level 25, 3 skill points, level 50, 2 skill points, level 75+, 1 skill point) or it could be ascending the exact opposite (level 1, 1 skill point, etc, etc, level 75+, 5 skill points)

These are two things I personally would love to see.
