Makes me feel like I'm on a railroad. Very negative. Don't like it. Why bother rolling if the GM is going to change the results to fit their pre-written story?
As a DM, I often roll the dice (then feign a concerned look on my face, and pretend to look something up, and shake my head ominously) and dont even look at the result.
The dice are a tool, not just a random number generator.
