I think that depends on whom you ask. Authors have different approaches on what, how and why they write. Some may even consider it the centrepiece of their art to describe complex matters in short, striking words and images. Wolfgang Borchert described the terrors of war and post-war life in short, striking sentences of subtle imagery. I guess he would have needed a different way to write if what he wrote about was burning people running out of buildings, but he chose to write about a boy watching over his dead brother in the rubble of their house. Same topic, different approach.
