Can we get a real Fighter Mage?
And not like
and
who are assassins.
Someone with a good amount of CC, a good defensive ability and deals some aoe magic damage.
Having a person deal magic damage on basic attacks in no way makes them a Mage Fighter.
EDIT: Ok so I basically see a true Mage/Fighter [And not an AP Assassin or Rumble :/]
As someone has short range abilities that do hybrid if not all magic damage. Whose abilities either reinforce basic attacking or need it to be applicable (Gragas out). Melee Based (Ranged Champs out) Who doesn't have insane mobility (all assassins out including Kass), who doesn't have extremely long ranged abilities (Rumble and Galio Out), who only builds a bit of defense to survive long enough to dish out damage (Ap Tanks out), Mostly Sustained damage not burst (Again all assasins out and Gragas) and finally who has average CC and utility.
So far the closest thing to it in League is
. Though he is a bit tankier that what I envision a Fighter/Mage to be.
BRING ON HELMET BRO!!!


<this is wukong

and
for example.
here.
He is not AA reliant, but he still fights his opponent close up. He is neither squishy nor tanky. Kinda fits the spot. ^^

Can we please top pretending lane Naut doesn't exist? He literally fulfills every single one of the qualities OP is looking for.
and
fit your criteria, and
and 

and healing with
on her, her E scales with AD really well, so the boost from passive along with the shield makes her un-squishy enough to be classified as a fighter if that is a requirement for you ;].
With CC and less damage
With no bandage toss
Pre-Rework with CC
With less damage and more cc
