All I'm saying is that I'm waiting to see what Big Finish does with her incarnation, and for the inevitable retcon for recent(ish) developments. My bet is the reveal of two Time Lords using the same name.
I'm laying the blame at Chibnall's feet not Whittaker's, because it's clear she's not where the problem is.
I'd also like to see the return of the War Chie. Sure, they're the same broad archetype as the Master, but if you stayed close to their characterisation from The War Games they'd be more like the early Master than their modern incarnations.
