Problem with Jelena is - she always speaks the truth but always at a wrong time. FIRST beat Wozniacki, THEN (rightfully) bash her game.
IMO she didn't bash her game.
she just said it the way it is.
In a way I admire that & she should say it the way she sees it.
Possibly it's her way also of saying, that over the last few years she was also having a hard look at herself, and possibly now she was fairly clear about herself, who she is, and what her own strengths and weaknesses are.
I actually see it as a form of strength.
I think that honesty with oneself is fundamentally the greatest strength that one can have.
In the end however you cut it being philosophical and cautious (although beneficial in short term), erodes you as a person.
