It's there to block high damaging, slow moving projectiles (hi morg Q) and for blocking AAs if you hve godlike prediction skills. without it, Eurya, who has the lowest hp and mr of any melee champion, would simply pop way too easily. The average human reaction time is 0.215, with the cast delay (just added) there should be a 0.285 second delay between the ability fireing out and "Linear"'s activation. so you won't be blocking any AAs unless like you mentioned, you're a god. As I just said though, it is there to help with slow moving, high damaging, abilities that also CC you for a long time. (so you don't get fcked that easily)
