The entirety of the rebalance provided the majority of the cast with good aa's, safe, strong pressure and great top end damage. So in that respect, she's actually rather average.
Her versatility is arguable, just because she has more options doesn't mean that she can handle more situations. For instance many of her abilities provide support to her pressure, either adding safety or mixup, however those same tools don't necessarily help in a defensive position. Her abare is also still questionable. With so many characters having such strong pressure, I'm feeling that defensive options will have a lot more influence in CS2... there are many reasons why she would have problems playing footsies or matching damage with much of the cast.
I would personally say Platinum is a strong character, even with an underdeveloped metagame, just keep in mind that... pretty much everyone is looking pretty strong.
