Honestly, I think this is a decent list. We got Beatrix, we got Agrias, we got all the best females in the series. Terra and Garnet are a lot higher up then I feared, Rinoa is nicely in tenth, far further down than I feared. I mean, there's no Freya, no Cissnei, but those aren't well-known superstar characters like Tifa. I mean, yeah, Lightning is on top when she has no business being there, but she's the highest profile FF character, and lots of teenagers all around the world have been fooled by SE's marketing. Give us the perspective of time, and Lightning will merely be in the top 10.
The only great female they're missing is Frimelda Lotice.
Fact: all fanbases are unpleasable, deal with it. http://i.minus.com/ixGBrDD4hclHn.gif
