A lot of people prefer that but a lot of people also don't take it seriously, think that was the writers being generous/promoting him multiple times was them being self-promoting to themselves and even those who do like it do admit well it was wartime situation advancements are/should be faster then given that. And OTOH that show despite having some promotions didn't really have likelihood or much possibility of characters being reassigned to elsewhere even though that's often thought of as also associated with wartime situation.
Nog's rapid promotion to ensign was the result of the Federation being at war and Starfleet needing to crew its ships. A lot of cadets probably had two- or three-year Academy careers during the Dominion war. And his promotion to lieutenant after two years is also fine. Data said that three years is typical, but Nog was a very capable officer and he saw combat. As I said, If the showrunners on Voyager had needed guidance on who and how to promote, DS9's promotions were impeccable.
- Sisko was a commander for between three and six years. We don't know what rank he held at Utopia Planitia. His promotion to captain occured about when it should.
- Kira was a major (LCDR equivalent) for six years. Considering that she was a resistance fighter previously and there was a learning curve to being a soldier, that works. In S7, she was considered equivalent to a Commander, hence her Starfleet rank.
- Bashir was probably an ensign throughout medical school and routinely promoted to LTJG as a practicing physician.
- Dax was 28, so maybe on the young side for a full lieutenant. But it's probably routine for Joined Trill to be promoted earlier than normal, due to their vastly enhanced life experience. This applies to Ezri making LTJG before her scheduled promotion date (she was actually Jake's age).
- Worf was not promoted on DS9... and he shouldn't have been. He was freshly promoted to LCDR, and was not due. He makes captain later on.
- And as I said, Nog's promotions were not out of thr ordinary for a distinguished wartime career.
