Regarding Frostbite 3, if it's CPU intensive, that might be where the issue lies since Wii U is apparently far more GPU centric. Perhaps it's not simply that Frostbite 3 can't run on Wii U period, but that it can't run without heavily optimizing it for the platform which certainly doesn't seem worth it all things considered. My understanding is when DICE ran some tests with "not too promising results," they didn't change anything to account for running on completely different hardware. Is it fair? Depends on how you look at it. They probably could have done a better job explaining why their tests yielded less than desirable results.
