you could argue that she is just building on something that Kazutoyo built.
Disagree.
Ive done all MSQ start to end at least twice, and you can TELL where she started..she may have had a basis on which to work, certainly ( Really, what writer doesnt? ) but what we see is HER handiwork and her gift. Every writer has a basis, a start point, a foundation to build on, agreed...but what she had been given is NOTHING, compared to what she created.
You could see it pre Shadowbringers, the tone, the settings, all carefully laid down in exquisite detail.
( Spoiler below, click at own peril if you havent done Shadowbringers MSQ)
Tesleens fate..dear God, it was at that moment it came home to me HARD....just how BROKEN the First was....soul tearing horror, leaving me shattered. One moment she is a woman..the next her body and spirit literally twisted, remade into an abomination of Light that had no memory of who or what it once was. I was literally in tears of rage
I can think of only a scant handful of game writers that had that ability.....to literally reach in, grab your heart , turning it to ice in one split second.
My guess is that she will be lead writer for the next expac...and I cant wait to see where it will take us.
