One feature i'd like to see
If somebody gets stunned/snared during a dash, the dash will stop. If somebody manages to land a stun/snare on somebody who is dashing, or somebody dashes into a stun/snare, it should stop them. To me, it makes no sense that you can dash into an ability to lessen the effects of that ability. And if somebody fails to use their mobility to avoid dangers, they should feel the consequences. Veigar's stun already works like that and Yasuo's dash already works like that. I see no reason it shouldn't apply to the large majority of dashes. (excluding abilities such as Vi's ult and Malphite's ult)
