Humanoid champions' model sizes makes no sense

The size among humanoid champs really bother me. Some are much bigger or smaller than the ones they should be rather equal to. And I don't mean the height as different people has different height. What I mean is even if, let's say, Ashe is proportional, doesn't have bigget head than she should, she is smalled than Xayah. Her model is smaller.

Let's talk with examples: --Ekko (male teenager) doesn't stay straight and is still the same height as Katarina (female adult). If he would he probably would be 10% bigger than he should. And I know males are usually heigher, but we talk here about model size. Compare him to Ezreal --Ashe should be the same size as Xayah

• Rakan is bigger than Jayce
• Annie, as a child is too big too, but this one is probably allowed to see her smoothly

If you could import all or even few humanoid champs into 3D program, you would notice the difference. I would like Riot to do this and see (in cm or feet) how big are some champions compared to others. I remember some time ago Riot adressed this, they changed size of Mundo, few Yordles and some others
