Are you guys leaving nerd pole-ing in the game? The way the game is played will be drastically changed taking this out from building to looting buildings. As it stands a player can get to where the best loot in the game is with two frames. Who needs a helicopter?! That's a problem right?
FYI, they did answer this in the stream (or perhaps an earlier stream, can't remember offhand).
Their solutions did not affect nerd-poling. One was to add one-way doors; the other was to have a door that requires a key, which is hidden in some other (random) place in the POI. In either case, the idea is that you can't go immediately to the loot room (via nerd-poling or otherwise) and just grab the loot.
Both of these ideas are better than eliminating nerd-poling IMHO.
For one: even if you eliminate nerd-poling, you can still reach those rooms in other ways. For example, building "stair steps" - frames that are attached to the walls, not immediately above each other, but diagonally above the previous frame. Eliminating this would make building bases nigh impossible (e.g. you couldn't build stairs at all in-game).
For another: several POI designers (not just at TFP) deliberately hide loot in places that can only be accessed by nerd-poling, and all those POIs would basically break.
EDIT: Thinking about it, I
really hope they add keys to the game. Think about all the cool crap that POI designers could do with that. It would not be long at all before some modder somewhere recreates the old Doom levels as POIs.
EDIT 2: Thinking about it even more - I really love the idea of Doom-style colored keys, and doors that could only be unlocked by using a key of that color.
This means you could have a whole bunch of POIs that have entire sections hidden behind keys of one color - and the key wouldn't even have to be associated with that specific POI.
Example: A difficult POI that has a "key helper" loot container that generates a key of a random color. For the sake of argument, let's say you get a green key card. You
could unlock the "green" section of that POI. But you could also use that key on a different POI, to unlock the "green" section of that other POI.
If the "key helper" loot container was associated with game stage, it would mean the same POIs could be hidden behind game stage, such that you could fully explore any of these POIs only after you are at a certain game stage. It would make each POI repeatable, and give players a big reason to keep exploring the same POIs at later game stages.
It would be especially effective if you consume a key each time you open a door with a key. So if you get a green key, you have to make a choice about
which POI you go to in order to unlock its "green" section. You made the wrong choice, you have to go loot another green key card.
