The fact that you can aggro mobs through the floor is absolutely AWFUL

[jack][s_On]

If you've played the game enough you know exactly what I'm talking about and for the new/unaware people there's one(really two) particular room on the Frost Map where its a big circle with a elevator in the middle. I HATE spawning or even having to go through this room at all and its so poorly designed its insane. The second you attack anything in that room you aggro everything thats below you and even if your trying not to make a ton of noise in there the garbage room design ensures that anyone even remotely close will hear the those trashcan mobs shooting at you through the floor and making a ton of noise. There's another spot on the same Frost map where there's a shield guy in the middle with a pool surrounding him and I don't know which room is worse TBH and they would be fine without this issue. The second you fight one of those goblin things 5 others aggro right to you and all of them are from the floor below you and its a nonstop chain aggro and can easily lead other players right to you while your fighting half a room right from the ♥♥♥♥♥♥♥ rip when all you actualy aggro'd was one mob.... I've lost track of how many times I've had people come into that room while I'm fighting too many things to notice and just get insta killed. I've died in that room 10x more than any other place in all three maps. A horrible design how its been in the game this long and not changed is sad as could be.
If you know any other spots like this feel free to mention them here. I'm sure there's others I'm not thinking of atm.
