Investing in mutual funds requires research which needs in-depth knowledge and lots of time. The knowledge can be acquired over time if you have right tools to analyse the performance. However, if you do not have the requisite time to dedicate towards researching and have access to right tools, then advisory is for you.
Advisors also serve as experts with whom you could discuss your ideas and get recommendations of schemes. A second opinion from experts will help you pick the best ones.
