Does Near Future Propulsion (KSP mod) get easier late game?

After playing Kerbal Space Program way too much. I added the mod "Near Future Propulsion" along with the axillary near future mods.

But now, mid-career it looks like the nuclear engine (everyone's go-to engine) is totally nerfed and useless.

My question is: does Near Future make the game easier late game? Are there good engines coming? Or did NFP just nerf everything?
