Kennen and Alistar Gameplay Bug

Whenever I use Thundering Shuriken with Kennen, I have noticed the shuriken is animated a bit farther than where it actually hits enemy targets. For example, i throw my Thundering Shuriken (Q) at the enemy champ. The shuriken animates long enough to pass all the way through the enemy target while overextending its highlighted throwing range, but no damage is assessed when it overlaps with the enemy target's outline or silhouette. The same thing was happening awhile ago with Ashe's Volley if you remember.

Another champion's ability that really bothers me is Alistar's E. When he roars why must he stop moving entirely to activate the ability? He should be able to keep on moving while activating it, but this is just my opinion. Thank you for your consideration!
