Dolls, Rooftops and Teen Room are 3 Large open maps that allows you to see where you want to go and figure out a path on how to get there...
Lost temple on the other hand is not an open map it's more of a maze with lots of small hallways and corridors. so unless you know the map very well you have no clue or reference how to get to which are or spot on the map. (not to mention trying to track down the last couple of innos who are moving around randomly in that maze...just pain)
idk about it being like a maze, the corridors are indeed tight, but the pathways are pretty linear and easy to navigate with plenty of landmarks to go back to. Plus there are the pit teleporters in rooms with the tombs where it leads you back to the middle stairwell coming back. As for tracking down, the last couple of innos, not an issue for the most part as this map is heavily traitor sided with all the traps and most of the corridors being a beeline to the next area corner of the map.
Now on the subject of Dolls, Rooftops, and Teen Room. While it's true you can see where you want to go, you can't anticipate where people are going to go with that much verticality which causes issues with people delaying by running up and down and around the map, even with the upgraded radar perks. Sure, you can camp and wait for them to peek out but the issue is it's most likely not going to happen if they are aware of the situation and will take obscure routing to avoid making contact. Especially with these three maps that have so much cover with their verticality: Dolls with their vents and ladders in the wardrobe closet, Teen room with the vent travel, drawers and shelves, and Rooftops with the amount of buildings you can take cover in and run quickly out especially with the aid of Tom Selleck's Secret rewards.
Meanwhile with Lost temple cover is limited from room to room, and pretty hard to delay/nonparticipation from the innos. The rooms all lead to one other corner to another, it's barely even a maze tbh. It only takes 2 playthroughs for a person to actually learn the map and they can easily spectate to see where each corridor leads to. I'd say the map is pretty balanced for both inno's and t's, since it requires critical think on the t's for the most part and heavy trigger discipline for the innos to not crossfire.
