Possible insight on Azir bug

Hi,

So I play a lot of Azir and I usually do not run any cdr runes. I was just testing a cdr rune build on team builder to try out different itemizations that required less total cdr and found out that his soldiers instantly became twice as buggy as usual. It was almost like they couldn't decide when and if they were applying the increased cdr from the runes. I twice saw a soldier attack half way and then the attack reset attacking again but doing no damage on the first one.

This was really obvious when using the scaling cdr quint. It happened less using the cdr glyphs. I've always had the cdr sorcery mastery and that doesn't seem to affect it (as far as I can tell).

Should be able to replicate it testing out scaling cdr quints. Must be related to how it applies the cdr from masteries to Azirs attack speed.
