So hey, I'm making a map, and I have a basic layout for it in mind, but as I build it I want to make sure that there's something that can be found useful for all the classes. For instance, I try to insure there are a noticeable amount of corners for pyros to hide behind, or large walls for soldiers to jump over, or corners for engineers to make mini-bases. That kind of thing. But I'm having some trouble with the scout, as well as the heavy. I don't play these classes often, and as a result I am left with a less than knowledgeable understanding of them. What are some features in a map that can be implemented to accommodate these classes? I understand some things like the raised platform in turbine for scouts, but I know little outside of that, and completely nothing for the heavy. To expand on this subject and make this thread more interesting, feel free to explain design theory for every class.
