I switched to mod on WoD a few months ago, after i lost my old project in a harddrive crash. Personally, it still feels alot like WotLK modding, but the db2 files and FileData are a pain in the ass. I mostly figured the db2 stuff out with using DB2Editor, but i just hate the FileData system. It was way easier to just write the line directly into the file, instead of having to keep track of every single number. It is also extremely annoying, when you create something that worked in WotLK, but crashes on WoD for whatever reason (it took me so long to figure out how to add a new continent). WoD modding is possible, it's just hard and requires more time to figure out how to make stuff work (Which i think is what scares many people off modding on WoD)
