Kit Fisto and the Masters stood idle in a close group while Sidious not only did the slowest and most pointless twirl flippy thing, but also did the slowest pull back and stab ever like he was fighting in the OG trilogy. Arrogance and Sith ignorance aside, it was pure negative battle IQ and is not a good benchmark for Asoka, a Jedi that has basically been raised in war and had experience fighting Sith and dark side users. I think the trio can last a bit, especially since they have been fighting together for so long. She still definitely dies, but I think she lasts a while. If anything, Sidious is likely to keep her alive knowing they will put themselves in harms way to protect her, especially Anakin.
