Read between the lines and it looks like EA is making this their go to engine.
Don't even need to, they've openly stated that all future EA games will be made on Frostbite. They're making it the new in-house engine, cutting costs all across the board with all their studios working collectively on the same engineering.
Makes me wonder why they chose the FB3 engine if it wasn't even geared towards RPG's...hopeuflly not just because of the multiplayer portion since I honestly couldn't give a rat's patootie about it.
Either way, I'd be happier if they would just give us turtlenecks over creepy necklace/seams if it's something that can't be fixed. 
Engines aren't really geared towards anything - they're just software you build more software upon. FB was originally developed for one game, but what BW has built upon it for the RPG format (talk tables, loot tables, plot branches, etc) can be used for any game in return, even shooters, racing, etc.
In any case, the neckseam doesn't really bother me (I've been living with awful neckseams since ye ole days of modding Morrowind, so this level of throw-a-necklace-on-it doesn't even register anymore); but some modders have made the necklace on the dress very minimal, such as Daria's retextures, and others like Elle's kept the big golden acessory (I think it works with the overall look of the retexture though), so at this point we're fortunate enough with diverse mods that keeping the dress' neckline clean or busy is a matter of taste.
I find PJ recolors that are done only for the lightest of the light skin tones and offer no alternative for darker-skinned Inquisitors more annoying than the tiny necklace on the dress, tbh. Many a PJ I have wanted and could not have because the modder stopped at the "snow white" neck/arm complexion and didn't bother with the rest. Fortunately the dress doesn't seem to need specific recolors for each skin tone, it's been working fine on all my Quizzies so far with no major discoloration issues
