Well in my humble opinion there are two possible reasons as to why the H shield doesn't block lasers. I'll let you decide.What would cause Link's Hylian shield to not block a Falco's projectiles? I was just playing against one online and he liked to spam lasers. I figured I'd just walk up to him but every laser damaged me. I tested against the AI and his lasers hit me as well. Is there a category of projectiles the shield won't block? I was under the impression (and I have read everywhere, including in one of the major guides on this board) that the shield is supposed to block pretty much everything, "even a reflected, previously pocketed fully charged Samus Charge Shot" as one guy said. But not tiny lasers? It even blocks Mega Man's crash bomb explosion.
The first is that a decision was made to deliberately program the game to be that way for the sake of balancing.
The second is that lasers have transcendent priority and that the Hylian shield works by holding out a passive 'hitbox' to clash with what the game has deemed to be a projectile (and therefore can also be reflected), only you can't clash with transcendent hitboxes and so transcendent projectiles are an exception and it makes sense that the H shield wouldn't clash with them.
The problem with the second theory (which I personally find more appealing) is that there are other random exceptions (other than the lasers) that can be reflected but cannot be blocked by the H shield, and none of them are transcendent projectiles. The H shield won't block returning boomerangs or Villager's Bair (yet it blocks the front on boomerang and the Fair just fine). It's up to you to decide whether these were deliberately programmed to not be blocked by the H shield or whether they were mere oversights. If it's the former, then you'll go with the first theory; if it's the later, then the second theory holds up.
