As discussed in your other thread - the process as it is is right and will not changed.
-
Envato get thousands of submissions and feedback would either require a huge investment in staff, or create huge delays, or end up being generic and counter productive.
-
In a premium marketplace it is not the reviewers’ responsibility to teach authors design or code basics
-
they already do offer feedback when items are close to approval
-
More than anything - you only need to look at some of the submission rejections in these forums to see how mis-guided and far off a big % are. If a reviewer gives even broad and quick feedback like improve typography, then there is a tiny chance that most will be able to effectively comprehend or action that, which will in turn lead to more delays and more frustration at both ends.
With respect your other thread is a perfect example of why this should not happen - you had feedback from very experienced authors, none of which you either understood or actioned, so why should reviewers or anyone else bother to give more detailed feedback to the thousands of submissions they get?
