Please-please make it possible to turn this kind of crap off - switch in options or no level scaling on harder difficulties would be great. I do know that you need to cater for console-gamers, who can't hack their way out of wet paper bag even on a good day, but this is no reason to punish the rest of us.
I oppose level-scaling as much as the next guy, but there's been millions of threads about that already. Also, I'm offended.
