first of all, i love how all your examples are from either from the last couples of years or during the attitude era and are all feuds that nobody really remember or cares to revisit.
Having said that, you really should watch some older wrestling that happened before the attitude era, when you we're still able to tell a story without being force to do lazy booking like they are doing with this feud or all the feud you mentioned as example. I know that wrestling and it's fans have chance since the 80's and early 90's but the fundamental on how to booking are great feud are still the same. Have your babyface chase the champion, fail, get back up, go through some obstacles to get your rematch and then on PPV you go and have you babyface challenger beat your heel champion. That'S wrestling booking 101 and that's how a memorable feud is build. Then after the babyface champion won the belt, the heel champion gets his or her rematch and fail and you move on with another challenger until it's time to revisit this feud.
Right now, this feud could have been so much more if book correctly because while they have done some great matches, it'S just that a series of great matches and they are position as the 2 women's that are getting all theses groundbreaking stipulation matches and main event and you're not really connecting with neither character. From what i've heard from somebody that was in the crowd last night, most of the fans we're confuse about who to cheer for because they wanted to cheer for charlotte but we're kinda forced to cheer for sasha because of the ric flair dedication. So both girls aren't over, their matches are.
If it was me that was booking that match, nia jax would have interfered in the match costing sasha the championship and this would have lead to a match between sasha and nia and charlotte would have gotten into a small program with bayley and i would have keep the ultimate match between Charlotte and Sasha for wrestlemania next year. This way, you get new feud for the raw women's roster while still not really forgetting about this feud and keeping the big match for mania and you have sasha finally beat charlotte on PPV in the ultimate wrestlemania moment.
