In general, the designer has an unpleasant sense of taste, the design concept is developed unpleasantly. But on large projects (100+ pages) to work is hard, as attention leaves to want the best. Too many rounds of rounds that arise from the designer's fault, the responsibility for which it translates to the customer ("who did not find all rounds immediately and did not inform the first rounds of rounds"). Therefore, for not very extensive projects I recommend, and for scale no, because you will have to look 100 times, whether there were no new errors after a round of straight.
