All right, so overall, the damage is fine when there are no pets being used, because as I mentioned, there are moments where nothing happens with Army of the Dead due to other abilities taking priority over the runes. I watched closely, and it took a full minute before the sequence finally activated Army of the Dead. The problem is that when you go into a fight, you want to use that at the start, which means you lost one minute where it was not being used at all.
When it came to Soul Reaper, it was very inconsistent. When Army of the Dead finally did activate, Soul Reaper did not even go off, which is exactly what I expected to be an issue.
I think the sequence, as it currently stands, could be drastically improved by applying modifiers to Soul Reaper, Dark Transformation, and Army of the Dead. For example, you could press Shift to trigger Army of the Dead and Dark Transformation together, and press ctrl or alt to activate Soul Reaper. That would solve most of the usage problems.
Also, looking at the sequence, you have way too many repeated skills. When the sequence runs, everything is cycled through extremely quickly, so you do not need double or triple copies of the same skill in different blocks. You could easily reduce this by having only one of each ability, for example one Death Coil with modifiers, one Scourge Strike with modifiers, and so on. You do not need Scourge Strike, then Death Coil, then Scourge Strike again in separate blocks. It is an unnecessary use of blocks.
You could definitely clean it up quite a bit. Otherwise, the damage is fine. I just do not understand why you have so many blocks for each individual skill when they can end up being skipped anyway due to a lack of runes or runic power.
