I have to say I agree with this, I mean it's fine for those people that want to grind away in the arena, but as you said, on insanity difficulty it gets very tedious. At this point I have trouble just getting enough credits to buy more than one of the weapons I like to use because they're all 125000 or higher. It just feels as if the amount of money you get from the game if you don't grind for hours on end in the arena, and the price of these weapons and armor are completely unbalanced. I mean this is a single player game, I don't see why they can't balance out the prices a bit better so that people can actually try out multiple spectre weapons in a single playthrough without having to grind forever.
