Runes based on game difficulty

[gunnyhighway]

Does anyone know if you get more runes based on the game difficulty?

I am thinking about my second playthrough and my first was on easy. And ofc it was really easy. I want my second playthrough to be much harder but not on my gold and runes. I want the battles to be more difficult. Top that off with I have this OCD thing of wanting to get a crap ton of runes, I was just curious.

I just want more of a challenge out of the fights themselves making them more tactical and not so much kiting around all the maps trying to find runes and gold making it boring.
