[GAMEPLAY] AA and on-hit vs blocking, possibly dodging and blind

Pantheon's shield is supposed to block ANY given kind of aa damage and on-hit effect, as updated in V5.22. However, tons of effects still goes through Pantheon's shield. For example, Tahm Kench's passive somehow goes through the shield when he AAs Pantheon when the shield is on. Also, Darius's passive cannot stack/refresh anyhow when Kayle has her ult on, but again can somehow goes through Pantheon's shield. Riot should take a deeper look into the blocking mechanics.

I haven't look into other interactions of dodging and blind with other effects though. If anyone knows better, feel free to leave a comment.
