Battlefield is not an RPG where mods would be in high demand.
On the contrary, the Battlefield games have traditionally been hugely popular for modding. Battlefield 1942, Battlefield: Vietnam and Battlefield 2 had heaps of hugely successful mods. Mods in this sense are the Total Conversion mods, where the game is totally modded to make a completely different experience. For example, Battlefield 1942 has you taking part in the battles of World War 2. Desert Combat, the most succesful mod for Battlefield 1942 which even overtook the popularity of the core game, totally converted the game to have you fighting in modern combat during battles in the Gulf War and other post Cold War scenarios. DICE even hired the modders of Desert Combat to help them make Battlefield 2.
The Frostbite 3 engine, which was developed by DICE for Battlefield 4 and is the engine that Inquisition uses, is not an engine that seems to have been designed with modding in mind. There are no public development tools and the engine uses a lot of proprietry file formats. It seems to be a trend these days, because publishers have cottoned onto the idea of making money off DLC. In the past, especially when games like Battlefield 1942 were popular, that extra content would have been released for free by the developers and they would actively encourage modders to create their own content. These days however, DLC is worth big bucks to Publishers and they're probably not that willing to compromise a revenue stream by encouraging people to make and release content for free.
