I was doing some comparisons of Demo sim results vs Simulationcraft, and I noticed some discrepancies, and one meaningful omission on AMR.
Raidbots vs Not Available (11,353 dps)
To lead with the most relevant thing - the 4p imps don’t seem to have their Doombolt (the damage they do when they expire naturally) implemented in AMR at all. I assume this makes the 4p show up as less valuable than it actually is - though it likely is still suggested in all relevant situations. This accounts for a meaningful amount of the difference between the two sims.
The other major difference is in Demonic Tyrant damage. The Simulationcraft result has a significantly larger amount of damage from Demonic Tyrants, so I assume there’s a rotational difference that gets it more value from Demonic Consumption. Not sure if it’s some fiddly simc-only optimization or if they’re doing something meaningfully better.
The rest of the damage difference is in Dreadstalkers, Imps, and an incorrectly scaled Infinitely Divisible Ooze (on both sides! Mine does 1442 damage per hit, and neither sim has that number). The Ooze, of course, does not matter, given that the trinket is no longer relevant.
