ROIT, who are the mages under the radar?

So, riot announced a major mage update. From what i see it would affect and , but who else? I can imagine some of the champs that need help, but it would be only speculations.

I understand that upgrade is in fairly early stage (if they have even started working on it) and maybe it's too early to have clear answer, but at least some approximate info?

Sorry of this was already discussed and said, I apologize if i had missed it. Thank you all for taking your time to read and answer. Have a wonderful day!
