Riven animation canceling with Arcade and Dragon Blade

Classic, Redeemed,Battle Bunny,Elite and championship all have the same sort of animation (even though i've never played with championship, and i really want it) Dragon Blade and Arcade are a little strange and it effecting my performance, which i think it shouldn't. Also sometimes when i animation cancel the auto attack sound comes out before I actually hit something and I think that should be changed. Thank you for your time P.S i think Riven should get a spell cooldown reduction so it becomes like it was in S5
