Draven has too many bugs,

Ok, back in Season 7 and early season 8, Draven had this bug where his axe would randomly disappear and would heavily outcome the result of the next fight. I didn't really think much of it. I found it annoying, but I didn't bother addressing it, it wasn't THAT big, but these 2 that I'm about to address do affect fight 'directly'. Ok I'm going to keep this short.

CLIP 1 The first clip, keep an eye on my cursor the entire time, and you should see my "Stand Aside" (E) goes some random place behind me; looks closely. https://imgur.com/31SISXG

CLIP 2 In the fight when my ultimate is on its way back, I direct it so it hits Ziggs, later after watching the fight I notice my ultimate did no damage on its way back to Ziggs. https://imgur.com/P2OIJDg

Thanks, all replies are appreciated. [draven-pose]
