One of the (very few) things that’s bothered me as a new player on Arcane is the nether highway. I like it as an alternative to rails, and the map is absolutely brilliant. However, with the shear number of exits, it’s often hard to keep track of which is the main line without slowing down to read every sign. I noticed this a ton on the orange line when i first joined; at one point, it has a triple fork, all three equally wide and official looking.
Now, everyone learns the lines closest to them after multiple uses, but the problem isn’t just those new players. It’s also problematic for people attempting to visit others, since they have to read EVERY sign.
My suggestion is that we alter the main lines to look distinct from the exit styles. What springs to mind is using colored wool along the base of the main line at every exit. That way, you would be certain not to get lost off the Highway map, and could see the proper path without slowing to read signage.
