Because I'm a kind of person who values comfort over work
If something is easy/comfortable enough for the gain, I do it, if it's not I skip it.
If using such an advantage is mandatory to be competitive and it causes too much discomfort, I quit playing. I doubt we'll ever reach that situation, although a careful planner AND user of this feature (simulating incoming battles) would have an enormous potential advantage over people who don't do it.
