Not really this post is burying the lede.

A 5e fighter gets another feature called "action surge" which let's them perform another full attack action once per short rest. This means that each time they get another attack, their damage potential for a single round of combat goes up by two attacks. This makes them about the best focus-damage Nova builds.

Well, outside of conjure animals and paladins because WotC fucked up hard with them (but that is getting fixed in the 2024 revision).

edit: Besides I remember the dead levels of 3.5e.
