Insanity difficulty is too easy

Yup, I know of that there are some combinations that makes the game easy, but so far I have refused to use them.  One combi shoots off huge damage whilst recharging shields everytime you shoot. There are some combi's that are overpowered and perhaps a mistake to have them in the game and honestly takes the fun away from the game(or perhaps creates a different type of fun when a player can run around the battlefield in "god-mode" feeling invincible stoking your ego as you go)... I sometimes see people use them then complain that insanity is too easy and wants developers to make it tougher. If it's too easy for you, challenge yourself and roleplay a pure adept with a pistol without augs.
