One parse doesn't necessarily mean it's superior, not by a long shot. Parsing for optimal rotations literally means nothing as it does not take into account the rng that comes with your standard hit ranges, crit% or the bl proc chance.

For some reason, your DoT opener parsed higher min/max hits than when you used Krietors opener and this is shown in both Auto-Attacks and your out-going abilities. The crit% on both parses are also noticeably varied and your opener also had a lot more hits registered, despite it being a shorter parse, which is odd to say the least. All of these would affect the DPS of the parses.
