Did you, by chance, read a novel called "Darth Plagueis"?
If that were the case, why didn't Sidious just kill Yoda with a finger flick? How was Obi Wan competing with RotS Vader?
Because Sidious was just elevated to a position where he was Yoda's equal, obviously. And Obi-Wan was "competing" in sabers with an emotionally destabilized Anakin Skywalker.
The shift in balance affected long-term precognition and foresight, not combative power.
You may, once more, go and read "Darth Plagueis".
There was a boost in the Dark Sider's power in general:
"All that mattered was that, almost a decade earlier, they had succeeded in willing the Force to shift and tip irrevocably to the dark side. Not a mere paradigm shift, but a tangible alteration that could be felt by anyone strong in the Force, and whether or not trained in the Sith or Jedi arts" - Star Wars: Darth Plagueis, Chapter 24.
There are power suddenly gained, directly attributed to the shift:
"On the same day they had allowed Venamis to die. Then, by manipulating the Bith's midi-chlorians, which should have been inert and unresponsive, Plagueis had ressurected him. The enormity of the event had stunned Sidious into silence[...]But having gained the power to keep another alive hadn't been enough for him." - Star Wars: Darth Plagueis, Chapter 24.
In fact, the newfound power led Plaguies to the following idea:
"Plagueis understood, too, that there were no powers beyond his reach; none he couldn't master through an effort of will." - Star Wars: Darth Plagueis, Chapter 24.
Before that happened, he was speculating about the power of the Ancient Sith:
"But had Sith like Naga Sadow and Exar Kun genuinely been more powerful, or had they benefited from the fact that the dark side had been more prominent in those bygone eras?" - Star Wars: Darth Plagueis, Chapter 5.
So, urm: The shift did affect the entirety of the skills as force user, not just some selected abilities. It even increased the midi-chlorian count of Plagueis.
Otherwise, how is Dark Empire Palpatine so powerful compared to his RotS incarnation, given that Anakin had restored balance to the Force?
Because, obviously, the entirety of "Dark Empire" was conceived before the Chosen One / Force Balance stuff was. 🙄
