A Ninja guide without mathmatical gook please?

[Jim_Berry]

This guide is probably what you are more interested in.

Within the guide, it says:
"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."

Why is it when I do this, people put so much focus into me by telling me Kassatsu should be with Raiton instead? I mean, I know that, but in dungeons with adds, I use Doton with Kassatsu, so I don't see what the fuss is about.
