I have played the game on Insanity from the first minute and i think its hard enough if you not invest in armor like the Hyperguardian. Maybe its just me being bad but i died a lot more until i developed the Hyperguardian set or i just got used to the game, cant tell. Now i cannot remember when i died last time which may take some away of the enjoyment factor but you can always go less tanky or consider the fact that how many bullets it takes to take down an Ancient Eiroch, an exalted krogan (cant remember the name) it can be a fair way to even out the odds a bit to be a bullet sponge.
