Hitboxes for maps and L.O.S balance for Yamaoka Estate
It's nice that you tried to balance out between the open lanes and the hiding, but personally, it seems like there's way too much going on Yamaoka Estate's map. From both survivor and killer perspective, it's way too easy to throw the killer off in that map because of way too many hiding spots, and honestly it seems kind of unfair for both sides because there's too many disadvantages.
When playing as survivor, it's way too easy to hide from the killer and disrupt your own line of sight. Every single one I've went against (even in higher ranks), they lost me too easily. All I had to do was hide in a bunch of bamboo, grass, or a rock and they instantly lost me. This map can get way too confusing too because of the lack of balance between open lanes and the grass itself. It's also difficult to see the killer at times and such because of how tall the grass effects are.
For killer, I also found myself struggling no matter who I played as and what perks I used to find the survivor. Even with crutch perks like BBQ or Nurse's. I'll know the survivor's last location, yes, but they easily disappear if they're right next to a patch of grass or a rock because of its height. (If you don't believe me or think I'm just a noob, call me 'blind' if you wish.)
Another thing to add; rock hitboxes are extremely strange. I find myself hitting things I shouldn't. i.e I've gotten stuck between rocks at one point, as well as bumping into corners that seem to be open as both killer and survivor. I'm not sure if spawned hitboxes can be buggy at times, but it's also present in other maps like Mother's Dwelling (the trees), Macmillan Estate variants, and the Temple of Purgation (building doorways, certain wall spawns).
I hope I've brought up everything the right way. If you have any other info about broken hitboxes and stuff about the map I've discussed, feel free to add on.
