The reasoning behind a lot of the stats need to be adjusted.
Jack needs reasoning in general, he should be comparable to ADAM Fontaine who planned to destroy the Tenenbaum's Sanctuary
Splicers should be canged to Wall level in general due to the weakest ones being able to rip through steel that can withstand pressure 6 miles underwater and punching through bullet proof glass, With maybe the Brutes at Wall+ just by how strong they are
Big Daddies need reasoning, being able to severely damage if not oneshot Jack
Base Fontaine should be superior to Brute Splicers
Delta should be superior to Big Daddies, and the Large Building durability needs to be changed to just Building level
Big sisters need their reasoning adjusted, theyre comparable to Big Daddies and can take hits from Delta
Booker needs reasoning, his Devil's Kiss is comparable to the Fireman's power which scorched a courtyard and the surrounding buildings, and yes he killed a Big Daddy
