As PEOPLE exclusively revealed Monday, Farber, 33, and Johnson, 23, will dance in the troupe rather than compete with celebrities — and fans are already revolting on social media.
“Please tell me Sasha is in the troop [sic] because he chooses to,” one commented on ABC’s Instagram gallery announcing the lineup.
“Literally going to be the perfect season but why are @dance10jenna and @sashafarber1 not pros!” another wrote.
PEOPLE’s special issue 25 Seasons of ‘Dancing with The Stars’ is out Sept. 15.
Farber responded to the outcry Monday night, replying to a follower who tweeted about “fans wondering why he’s not going to be a pro.”
“I’m very lucky to have such amazing support from my fans!!! I love them all,” he tweeted, adding heart emojis.
The shakeup isn’t entirely unprecedented: Farber went pro for season 17 before being bumped to the troupe for four more seasons.

He was promoted for seasons 22-24, most recently placing fourth alongside Olympic gymnast Simone Biles. And Johnson became a pro in season 23 but only filled in for an injured Sharna Burgess last season.
Dancing with the Stars season 25 premieres Sept. 18 on ABC.
