Okay, so...

If Catra is going to be sent to Beast Island, and Scorpia is probably going to follow her, what's gonna stop She'Ra from going full force against The Horde?.

The Horde's biggest strength against Adora is the emotional manipulation Catra could put on her, Catra separated her from everyone else every time they're on a fight, she doesn't let her concentrate and Adora is too attached to Catra to actually damage her, while Catra is shown to not be afraid of doing so.

I don't know if Huntara is going to be able to be as efficient against She'Ra, she may be on par physically, but without Catra she's gonna be able to be emotionally stable through the whole thing.

If Hordak kicks away Catra he's going to lose a big key to victory.
