Instead of saying why they are top tiers it's best to list the reasons why they wouldnt be and so far no one ever made that or provided at least a single reason for that.
They are past their prime which is only natural but everything else besides digital sales remain untouched, bear in mind half of the members already enlisted and they came from a very long hiatus without much hype from the company.
Are some people here trying to say that the #1 group in terms of revenue of the #1 Entertainment company in South Korea should not be considered top tier? SM was desperate to make all SJ members sign the new contract because they wanted Suju to be untouched due to their current popularity.
