it does reward quality, (expletive).
serena was ranked #1 with 12 or so tournaments because they were all awesome tournaments.
but justine and kim have dominated since shes been out, have won more titles than serena this year, and have played more in general.
for serena to still be #1 (while playing like 10 tournaments in 52 weeks) when justine has 2 slams and 8 titles would be bullshit.
the only argument that could hold water is if you say the ranking system holds kim's quantity of play... bc she hasn't won a slam, but she has wonj everything else-- 9 titles...
