SO cass has an interesting quirk

Didn't they call attention to that in the patch notes at some point? It's a way to protect you from yourself. I believe there's similar interactions with mana runes and manaless champions, but I'm less sure on that one.

You're 100% accurate about manaflow band and manaless champions. Also water walking and a no river map like ARAM

possibly, but not everyone reads the patch notes.

because:

A = they're never complete descriptions of all the champs and the old patch notes are hard to access.

and

B = most players dont care because it's not helpful knowing what was done if you dont know how it actually affects the champion in the grand scheme - which takes playing with the champion consistently in order to discover new bugs/quirks/unmentioned interactions/etc. since for the most part even the high tier players are only providing their best guess as to how something works from their point of view.

and lastly

C = it's easier just to follow directions from a cookbook.
