Its probably on the lowest difficulty.

which is fair enough if I was streaming so that people could see the Cut-scenes I'd do the same.

Some people are complaining about it calling the streamers "newbs" but we all know there just doing that in order to make themselves feel less self conscious about there pointless lives and/or tiny penises.

Maybe you can change the difficulty or not.
Or the difficulty increases while you play. Keep in mind that this was the BEGINNING of story mode we saw.
