So I tried a bunch of different builds as well looking to help folks with op's how I ended up gauging my DPS was to use the escaped rancor's on Belsalvis. Its a way to get some idea of how things stack up.

We always timed from first pull but it usualy only take an hour and a half or so and I have no data on something like 2:05

So we had this same problem today after about 15 tries we set it to nightmare mode and got though first try.

I have about 6 of the 49 blue versions but I have made 106 attempts on breaking down the blues to get an epic version still with no luck.
