BFE gets a major improvement through Fusion.
IIRC shotty and AR mags get a bit bigger, and both have better accuracy, reloads and weapon swaps can be done while sprinting, and a lot of enemies get alternative attacks. The tweaks to starter weapons don't sound like much, but they are absolutely transformative for the early game, and later horde fights get hectic thanks to all the tricky overlapping fire patterns.
Not a complete redemption, but a big step up.
