why the /castrandom in macros that only contain one spell? why not just a castsequence macro? or does this let you skip past spells that can't be cast right now, for whatever reason?

edit: I see why not a castsequence macro. this allows you to essnetially have multiple spells in one non-castsequence macro, so it'll go down the list and cast whatever's available, in order. is this also the reason they're /castrandom? (I've never used /castrandom before, excuse my ignorance.)
