It is certainly up to you, but a Notice of Intent to Deny is generally a serious issue with your case. CIS is issuing the Notice of Intent to Deny because they believe your case is deniable unless you can address the particular issue or facts raised in the notice. It is similar to an RFE, but a little more serious as CIS is going one step further with the position that your case is deniable as it stands now.
I think it is a good idea to at least have an attorney review your facts and review the Notice of Intent to Deny in order to provide a recommended response for you. I would recommend that you at least consult with an immigration attorney who can review everything for you and advise on proper next steps.
