Okay but can we acknowledge that the three amplified Grisha on Kirigan's side kinda slayed with their strategies and teaming up? I wish the Tidemaker (Fruszi) had had more time to develop her ice powers (and her character), plus the Squaller's (Nisho's) lightning!! I wish it had been taken note of and not just included for coolness, because it does call into question how the powers can be (safely) diversified and used together. In general, there is no one now left who knows the "traditional" training ways except Zoya. Unless they introduce some new character, the entire POV of the grisha loyal to the Darkling has been erased.
