NHF – new heroes for Heroes V 3.1.

I've set a certain rule for myself: some heroes are specifically designed for different timeframes, so the player chooses heroes thoughtfully.
There are already many heroes. A small distribution won't change anything.

That's understandable. Otherwise, you have to play according to the scheme: "play with whatever the random generator gives you initially."

Another question: I didn't see anything about this in the change log in the nhf folder or in the ewa description. The amount of experience needed to level up a hero has noticeably decreased. Where I used to barely reach level 31, now I can easily reach level 40. Is this due to NHF?
