Please remove XP difference on difficulty

[gunnyhighway]

I really hate that I have to get less XP for impossible then I do on normal or any other lower difficulty. I want the game to stay super difficult but I would also like to maintain the same level as what a lower difficulty would get.

Does this bother anyone else? I find myself not wanting to bother with impossible because of the xp issue only. There are plenty of other ways to make the game harder.
