Hail of Blades vs. Double Strike

To anyone who thinks it's a bug that Yi's Double Strike takes up two Hail of Blades attacks: it's not. It's just a case of bringing the wrong rune on a champion.

The AS is granted on-attack, but the attack is counted for Hail on-hit. Double Strike acts as an auto attack for everything on-hit, but not for on-attack. You do get a faster Double Strike for it.

It is not an auto reset, and should not be treated as one. You could complain about it not working because you feel like an AA-based champ should have better burst instead of sustained damage, but there's no use complaining that a rune is working as designed. (Since the only alternative would be to make Hail on-hit, which would make it unusable on anyone who builds Guinsoo's)
