Personally... trap doors are not that fruitful, takes longer to kill for the same rewards you would gain from clearing a normal catacomb, but, if you clear a catacomb first and get the map at the end, then it could be prudent to take a trap door... but no one has tested this out.
Theorycraft: I would suggest that in a group, you take a high level character [10-20 levels higher than driver] and go trap door hunting, just make sure that the high level does not get the final kill shot and test the drops the more you go down. Again, this has not been tested, BUT, if you are lucky to go down like 3-5 trap doors within 5 minutes time frame, it could be a good time to test the drops.

There are a few broken mechanics in this game that would promote game play diversity if updated. It would be fun to actually use them but it's extremely inefficient. You'll want to just ignore them.
3- Guardians- You need excellent gear to be able to do anything.
This is incorrect in my experience as a guardian user, I have carried many people on hardcore with mediocre gear even when 1 or 2 have been afk.
