Thought about mordekaisers balance

If riot were to, lets say, make mordekaiser unable to flash when his Q is up, would that help them tweak and balance out morde? in my perspective he's supposed to be this deadly metal tank of a man that will destroy you if you get even a little close. but gameplay wise he's barely tanky stat wise, one of the lowest movespeed champs in the game without any mobility spells and his damage output while decent can easily counter the rest of his kit by using flash. I know there's morde mains on the boards and i luv ya all since i loved old morde when i first started playing, so i'd like to know what people think of this. Also i'm to this day not sure if new morde is better built ad or ap or just straight up hybrid with tankyness, since trinity force seems to suit him so well but then his only ad ratio is on his Q
