This would make for a real different game with more depth if you had like 2 weapon sets and 2 skill trees to go down. You would have like nine points overall to spend and you get to choose how to specialize your character. Like for the assault, he either gets the fast shooting assault rifle or one that shoots farther with bursts. And when you upgrade one skill set he gets more armor and stronger bombs, but the other would give him high accuracy and bullet damage. You could go into hybrids of the two also.
