Could we tighten up Ornn's rear W hitbox

Did a little testing in the practice tool and it seems unless you are well beyond ornns entire hitbox (blatantly behind him and outside his fat box) you will still be hit with the final tick of his Blast Burn. Clearly, he spews/spits/breaths fire. If we're being realistic, the hitbox should start at the front of his model and go out. But this isn't the case, and while some would say it's easy to avoid. I find it to be the contrary, and difficult to avoid on anyone that lacks a non-target-specific instant dash (very few top laners have those) to get either away from ornn, to the side or to get behind ornn. This means in a majority of cases, I have to try to out walk an ornn, a champ with an average movespeed value (so he's about as fast as a majority of champs in the game). There's very little time to out walk this, as it's purely down to movepspeed. You either have it or you don't Ornn is faster than 29% of champions and as fast as 27%. So he's as fast or faster than over 50% of the champions, meaning none of them can out run him. Now let's count how many of those have a non ult, non targeted instant dash, a considerable speed boost or some other way to avoid it (eg vlad). I count 7 champs. So 7/82 champs as slow or slower than ornn, can even try to avoid his W.

His W must be reliable to a degree of course. And it is, it's hit box is wide AF to match Ornn's stature, and it seems to get a range boost on that final tick (the one that applies brittle). So please, at the very least reduce the rear portion of the hitbox to at least mid way through his model, or even better, make it realistic and reduce it til it starts at the front of his model. Otherwise how can anyone be expected to avoid it through ornn's fatbox and minion block?
