Even with that in mind, the 'easiness' isn't due to the job or rotation itself*, but how much it is punished and how easily it can recover from mechanics and mistakes. Only secondly to that can you take into account the complexity of the rotation, and how distracting it ends up being or how much mental space it takes - that is a form of resource management, albeit not a very visible one.

*If the rotation is genuinely difficult, the job is badly designed as you end up fighting your own job rather than the boss.
