They're in a group because they are friends, ad all are trying to change the perceptions of women's wrestling in WWE. This is why Sasha was hugging Bayley after their match Saturday, because above all else, they're trying to change what it means to be women wrestler's in WWE. That's literally the angle.

They're doing that by having the same tag matches over and over?
You know what the angles that got the women over as a main part of NXT were about? Not "changing the perceptions of women's wrestling". Instead they had actual angles and characters that led to the perception changing.
Paige saying "We're doing a revolution" and having 15 tag matches in a row isn't going to lead to the reaction Bayley got for winning the title after a long, storied journey.
