Just the "SCW Season 6" link. I expect it to go to league standings, which is what it did back in VGT days. Actually, if I remember correctly, it went to a page that showed standings for 1v1 SC/BW and 2v2 SC/BW. That page also had a call-to-action to join the various 4 leagues on it.
As far as the member list/standings thing goes, I'll continue that it's the UX (user experience) industry's best practice to not use appeal to tradition logical fallacy to make UI decisions. Especially when you consider you're not automatically ranked in Blizzard's ranked games just or making an account. It takes meaning away from the placement of lower level players and also hides their visibility from higher D rank players who would possibly want to play them.
This is also how it works on SC2 and the old SC ladder before winbot ruined it. Generally in any competition, you have to participate to place. If we're concerned about showing everyone who has signed up, that could be a different page. Another "easy" (idk your dev env) solution would be to just have all 0-0 folks show up after the lowest place participant. This seems like a good way to have legitimately representative standings while show members list like people are accustomed to (which I still don't believe is compelling data to make UX decisions).
