Yes, I see. In a way I do understand the point. Though, a good copywriter will want to take control of all things related to the copy, as in the text font, images related. etc. In my experience, it creates a lot of friction between front-end people. At the end of the day, it is the copywriter the one who usually wins due to my inherent obsession of testing everything. I've made companies get rid of so much web 2.0 fluff (and in the process convert more people into customers) that I always wonder if designers ever test anything.
