Breakable Walls should not be breakable at the start of the game.
I won't lie and say I'm not biased when it comes to buffs to killers as I mostly play survivor. I do dabble in the killer side often though. Still, I think this new "wall breaking" mechanic might present a problem if it spreads to all maps.
i dont believe killers should be allowed to break walls whenever they want. Depending on the placement of these destructible walls, loops (not including the god loops , I mean more along the lines of loops that are only really useful if you aren't injured already), might be rendered total dead zones before survivors can even make use of them. In my opinion i believe killers should only be allowed to destroy walls while chasing OR after a certain amount of time has passed (lets say, 2 minutes like Corrupt Intervention and then its fair game).
To me this new mechanic, while awesome for killers and adding more dynamic chases for survivors, seems a little unfair if killers can just break whatever walls they want right away. As annoying as loops are, they're essential to making distance from the killer. I guess we'll have to wait until the PTB goes up to see where and what such walls will look like.
Oh and please buff/rework Monstrous Shrine already.
