The tickets are not "novel"-length, they are about a few bulleted lists of the sections I mentioned above. In that case it is indeed way easier to review that a ticket only saying "do X with Y data."

Reviewing code is harder than reviewing text because code does something and has interdependencies and therefore must be correct in its function, do not mix the two. This is like saying an editor reviewing an article or novel is harder than actually writing the novel which is blatantly incorrect.

Most real tickets are more complicated than “Do x with Y data” and also have many interdependencies throughout the business
