Depends on what combo. All of these feel plausible in some way to me.
Personally, my biggest gripe is the Group Acceleration. This doesn’t belong on any dino outside of a cunning or a dedicated raid dino like Tuora. This, combined with the speed decrease immunity and her other moves and stats, is overboard.
I’m tempted to say get rid of the speed decrease immunity, mainly because it seems as though lately it’s been “slap speed decrease immunity and bam, powerful dino”. Seriously, nearly all of the best dinos in the game currently (Morty, Magnus, Hadros, Compsol, Gemini) are all immune to it.
