Critique my NIN rotation

There's something in that link I must comment on:
"Individual ticks of Doton will all be guaranteed crits if you use it with Kassatsu, making it one of the most potent AoE abilities in the game."

I used to ALWAYS apply Kassatsu then Doton, but many folks told me I'm wrong, that it should always be Raiton or Fuma. That guide says I SHOULD be using Kass with Doton. I really need to stop listening to people and continue doing my own thing.

Pretty sure they're talking about single target, if they're referencing AoE pulls then they have no business playing DPS classes.
