Making my map work fine on both classic and reforged have been a huge pain in the ass. Some of the sounds just plain refuse to work on classic (I had to manually convert them from .flac to .wav) while some of the unit models are immensely different so it's very hard to make them fit both versions. Plus, an area that looks great on reforged may look like crap on classic and vice-versa. Don't even get me started on lighting. Thanks, Blizzard.
