Doors atleast should be a consistent thing.
Not just saying easily created by mappers, but having the same setup.
For instance games need to be able to target these doors, get info from them etc, just cause mappers can make them easiler it may lead to maps having doors set up differently making it a pain for games that use different maps with different door setups.
Im mainly a mapper so its possible It isnt as big of a issue that I think it is, but if I had to suggest something for doors, something like a global component or global prefab would work best imo.
