Mass Effect Andromeda was a disaster. Months after release Bioware Montreal was eliminated as a separate entity. They weren't even allowed to make already planned DLCs. It became a meme because of poor quality. And a lot of blame can be put on Frostbite.
Inquisition's development was a disaster due to poor tools. Pax 2013 demo, for example, was faked because no one knew what gameplay would look like(A YEAR BEFORE RELEASE), and it was mostly caused by missing engine systems. Game turned out to be OK though.
I am having a hard time understanding what the Frostbite engine had to do with any of this. Anything you can point to besides your opinion on the matter?
Battlefield is a multiplayer first person shooter. It doesn't need a dialogue editor, save system, third person camera, a lot of systems that help support advanced AI, and many other things that the Bioware game would need. Hence Frostbite didn't have all these things. They needed to be developed from scratch DURING the production. Which means half of the team was unable to work properly due to the lack of tools.
ME:A and DA:I had dialogues a save system, third person camera, etc. Why were they disasters if they were very successful in their own right? I don't understand what you are trying to get at.
Seems to me the engine was perfectly capable of doing everything you wrote it can't do and both games were successful deliverables.
