Aggro through doors/walls, line of sight
 

Mobs aggro through doors and walls. I remember this was fixed on live because at one point I used to pull mobs through locked doors through proximity aggro like Najena, and it was nerfed to prevent that (pre kunark).

This makes dungeon crawling much harder than it should be, you go to kill something in a hallway thats alone only to have every room with closed doors around it come flying out at you (permafrost, mistmoore). Another example, I was in runnyeye, i sit down to med next to a wall, and the mob in the room next to me aggros and attacks, bringing his buddies too.

Also shouldn't doors block line of sight. If a door is closed, I shouldn't be able to cast on something inside. Nor should the mob be able to cast on me.

Don't think doors are supposed to block line of sight/agro

walls are though

Walls in outdoor zones were equivalent to no walls at all -- see plane of hate -- you will recall upon zoning in somehow being bumrushed by the roaming trash mobs out of "nowhere" when they aggroed through the wall.
