Out of curiosity, I know that your companions had augmented Campaign gear and you had augmented Campaign + some augmented Dread Guard, but how much Dread Guard did that take? 2/5? 3/5?
I only have one Dread Guard piece (the legs), out of which I was able to use only two of the mods. Eyvan has the Dread Guard off-hand, which probably made a more significant difference. I suspect we probably could have done it with just straight augmented Campaign, seeing as the difference between Campaign and Dread Guard is quite small.
