[Gameplay] Master Yi Bugs after patch 5.13

Ever since Sated Devourer was released to live, Master Yi has had 3 bugs that have not been addressed.

1. His alpha strike cooldown is supposed to be reduced by 1 second for every auto attack Master Yi does. Before patch 5.13 his passive "double strike" would reduce the cooldown of alphastrike by 2 seconds because it was counted as 2 auto attacks. After 5.13 his double strike has not been reducing the cooldown by 2 seconds. Steps to reproduce: use alpha strike on any target. auto attack 4 times and keep an eye on the alpha strike cooldown, on the double strike you would expect it to reduce the cooldown by 2 seconds but it only reduces it by 1. Reproduce ability: 100%
2. Ever since Sated devourer was released to live in 5.13, using a health pot while fighting dramatically reduces your attack speed. This makes clearing the jungle more difficult as it has only happened after completing devourer, but before sating it. Steps to reproduce: play a game long enough to get enough gold to have devourer and 1 or more health pots. Go fight a jungle monster and activate a health pot while keeping an eye on your attack speed stat. You would expect your attack speed to stay the same, but it decreases. Reproduce ability: 100%
3. In a video where the sated devourer was on the PBE, master yi's alpha strike cooldown was reduced by 2 seconds every time the "shadow strike" from sated devourer was proced. However in live, this is not the case. Not sure if this is actually a bug, or just an interaction Riot didn't want for Master Yi. I'm fine with either, as long as: if it is a bug, riot fixes it, or if it's not a bug, riot addresses it in some way.
