For example, method 1 of doing something (say A) requires something else (say B). And I invented method 2 to do A but without the prerequisite of B. I can say:
The disadvantage of method 1 is its requirement/need of B.
Now I want to introduce my method by saying
the advantage of my method 2 is its (the phrase).
What should I put in there to represent the meaning of "no requirement/need of B"?
I don't choose to say "the advantage of my method 2 is that it doesn't require B" because I want to also introduce other advantages, like "the advantage of my method 2 is its speed, efficiency, and … ". What should I put here?
