It isn't even a discussion. Just pointed something out.
But I see you've more to add..why don't you make a contribution to the thread, then?!
I've was going to when it first opened, but before I got the chance it was already derailed. I think the OP and several others made some interesting points, most of which I agree with.
The interesting thing is to ask to what extent the strong points can compensate for weak ones, and to what extent weaknesses can be reduced or eliminated through training. Of the top group of players, I'd say that Vika has the best prospects of reducing her weaknesses, mainly by improving her serve. I can't see any reason why she can't develop a substantially better serve than she currently has. Given the fact that she's so hard to beat with such a weak serve you have to wonder how good she could be with a good serve.
I also think Aga's game is still improving, and despite lacking any great power she is capable of hitting quite a few winners. In fact I think for her the most scope for improvement is in her tactics: I think she still sometimes tries to outfox her opponents when she could more easily just go for quick winners. And although she's never going to have a huge serve, it must be possible for her to get a bit more potency into her second serve than she currently has.
The challenge for Angie is to develop a bit more of a plan B to her game now that her opponents have had the time to work out her counterpunching game and come up with tactics to deal with it.
I think Sara already does an amazing job given her stature and relative lack of power. She has a beautiful game and can make life difficult for most opponents when conditions suit her (and even sometimes when they don't), but I really don't see what she can do against hard-hitters other than what she is already doing.
It goes without saying that Petra is currently underachieving. Even if you accept that she was maybe a little overhyped last year, I think it's clear that she has more to her game than she's shown this year. As long as she's motivated and patient enough she should be able to regain her spot in the top 2-3 at some point.
For both Sam and Na the main limitations are mental, and given their age it may be unrealistic to expect any great turnaround in their games, although I think there are signs that both of them are very capable of being mentally tough when they put their minds to it. I Na's case the problem has been a disturbing tendency to effectively give up when the chips are down, but I have the impression that she has shown a bit more fight lately. In Sam's case it's not that she gives up as such, as that she lacks the kind of killer instinct that allows most top players to dominate lower ranked players.
Finally, Caro needs to figure out how to add some judicious attacking play to allow her to get more out of her excellent defensive game. Contrary to what a lot of her critics claim, she does have a decent attacking game, as she showed in the Moscow final, but she often has trouble finding the right balance between attack and defense, and when in doubt she still tends to fall back too much on the tried and trusted defense. She needs to take more risks.
