IMO, Sleepy Gimp should have either (in order from what I'd have prefered from most to least) 1) let Nancy be competent and actually oppose the evil characters 2) let Trixie be competent and actually oppose the characters more evil than her 3) have the LeFey aunt put Evelyn in her place and make clear she only got away doing her thing thanks to privileges she just lost 4) have Violet and Evelyn break up for good and have Evelyn struggle with her accomplice becoming competition.
Instead Sleepy Gimp decided to remove everyone's competency and just write "and Evelyn wins" at the end of all his scenarios.
Back in the days, it was subtly established that Violet was better at making plans and executing them, but that if she was bested at any point it was basically game over for her, while Evelyn was sloppier in both planning and execution but that she was generally good at turning the tables on people who supposedly had her at their mercy. It's a pattern you could see in the White Snake story, the Selene story, and a whole bunch of other instances (like how Country Girl actually managed to escape the LeFey manor while she couldn't do the same with Violet's appartment).
Then Family Value arrived, and Evelyn just started winning everything, with any setback in her way actually being something that'll help her succeed even harder in the future. On top of getting legitimately superpowered drugs and retaining her "you thought you had me but I can turn that to my advantage", she also got narratrively-contrived super-luck. While her actions got sloppier and sloppier.
The whole "Evelyn does stupid stuff and fails upward" trend has been going on for years now and it's just boring.
If you want a story where one character always wins, you either have to make *how* they win interesting, or make the fact they win something funny. This is neither.
