Props arent horrible. You dont have to make everything out of bricks to be good. Props are very useful all the time, and props make alot of things look better. Take a computer for example. You cant make them look good while being small at the same time. Another thing is fridges. Fridges look like stuff no matter what. Props fix that. Period.
I say something is horrible, I must be referring to how it is the lazy way to build...
Props are made from .dts file which means they cannot do the same things that .blb bricks can do like disappear, or fakekill, or stuff like that, and because of that, it causes a lot of console spam.
