The red lines are paths that are obscured by map terrain. Compare this to areas like Grotto and North Passage where there are overhangs which should obscure paths, but they've been cut away in the map.
The blue areas are overhangs that don't really obscure paths, but I thought I'd include them anyway because it's also inconsistent. The marked overhangs are only an issue south east of A where they make the obscured path even less noticeable, due to the lack of indents.
These obscured pathways are another barrier to entry for new players, making navigation more difficult if they haven't memorized the map by heart. This is top of the too similar player icon borders (white vs blue), which makes finding one's own icon more difficult for new players as well -- at least in a map that isn't centered on them (minimap).
