I got to step 8 and got 2 of the 3 Siva control grids and the group couldn't beat the end quick enough before I had to leave. Do you know if I have to just start over on step 8 or get in with a group again on the last boss or can I start in the beginning and just get the easy one and it would count? Im a warlock so I know I gotta have a titan and hunter who've done it or on the same step. Just not sure about the step 8..
