Auto attacks Animation, Sounds, Not lining up.

So, I've been playing league all day non-stop. And I've found that SOME champions their animation don't line up with attacks, MF's Auto's you see a redline around her pistols on her default skin, But that doesn't mean she actually made her auto attack, It's not the only champion especially the OLD champs are kinda meshy, When you hear the sounds, The auto attacks aren't actually done yet, Champions that do not have this such as yorick, Play so much more entertaining because being able to cancel animations beter and faster, But olaf and nasus sounds come before the auto attack hits, Animation is off with the hit and so on, And I actually manage to mesh up because of this, Is this just because I have a old computer?

Also Urgots Q -.- When it hits the ground it takes 0.1 seconds or so to actually do anything, You have to take in to account his Cast time, Rang, And you have to take into account his Delay of activation, and it feels so meshy to play such a champ, His kite is nothing wrong with it but he feels so buggy
