Unit needs path 2-5 abyss compared to path 1

Giuliameij

Hi Guys,
Assuming you have all horseman, and the extra counters needed per path. How many more units do you feel are needed for path 2-5 compared to path 1.
Otherwise, you could also put how many units you used (roughly) per path like this:
Path 1: 4k
Path 2: 5,5k
Path 3:............. you get what I mean.

Curious to see how they compare purely unit wise.
So I might be able to plan my future in this content.
