Actually you want my opinion. There’s 2 big fandoms still in this fandom that ABC needs in order for the show to survive past S7 but it won’t so it doesn’t matter.
Those two fandoms are the CS fandom and the ER fandom. And since ER and CS shippers are always at war with each other if you focus on one you lose the other. Wrapping up CS and giving them a happy ending sends the CS fandom away and then they can just have the ER fandom for one more season.
I know people don’t want to admit anything but Regina is very much a divisive character in the fandom especially after all the focus she’s had this season. Which has not been well written whatsoever. She’s as much loved as she is hated, especially going by Adam’s mentions and things on Twitter. Her and Hook are this way and have been for a while now.
