I searched the forum and did not find any topics answering this question: Is a mutilate better or vorse than combat spec when it comes to grinding experience, if each build use equal weapons, let's say GM weapons..

Pick either of these threads to ask for that:

I haven't been following Rogue discussion much but the last time I skimmed over a discussion was that Mutiliate did slightly less DPS than combat. But like I said I only skimmed through it.

Since I am bored: The discussion starts at about post 2189 and goes on for some pages with stuff I am too daft to understand. :P
