I have just received an email from the editor of a major journal in my field (engineering). He's rejected the paper, but advised me to do some modifications. These are his words: "..thanks for submitting your paper to "...". While the paper is well written and structured I see several limitations in the assessment of the method. I am rejecting it for now, but it could be reconsidered if the following issues can be addressed: MAJOR 1. 2. . . MINOR 1. 2. . . ..."
Minor items can be done easily. Major items, I believe, are not necessary. Most of relevant articles do not include them. My question is: should I do these modifications and resubmit the paper to the same journal, or consider submitting the article to another less IF journal to save my time? What are the chances to get published if I did these modifications.
