About Tahm's 3-stacked Q

Let me start here: i love Tahm's kit and design, i think his theme and gameplay match perfectly; but when i first saw the effect on the empowered Q (the stun), i was a bit disappointed. Why not change the effect into a knockback (just like an invisible maokai Qing just in front of the enemy)? I don't know how hard would it be to code, but for sure the results would be worth the effort! The stun just seem a bit lazy in this situation, since the expected effect of such sticky buttlick is more likely to be a displacement in the direction of Tahm, just like he's trying to catch them to eat them, but not quite succeding. In my opinion this would refine a kit which is already one of the most coherent and thematic in the league.

PS: obviously the entity of the cc intended for the spell should remain the same, only in a different form.
