To a degree, yes. On mythic you can only have one person per pool in P3, so you have assigned pools to enter to ensure everyone gets one. The arrow would help find your pool quickly on the map, but with the nerf, you get a lot more time and you can sit in your pool earlier.

For P1, the map helps in showing the position of the heart placements, but you don’t need your player’s arrow as much since the spots are much more spread out.
