In the matches I've played in A- if the team has chargers they always sit at these spots
and focus on the slope while keeping a slight eye on possible flanks. Since I use ninja squid getting to them from the sides is easier for me personally than going from the center. (this also varies based on my teams positions on where I go) If I have to reveal myself to shoot the slope to traverse up it. that's a window for them to snipe me. And they will. However they usually never get the chance, because I'm always making sure our team is in control of the 3 big charger spots and the zone itself.
I do personally enjoy this map on splatzones for the sole fact of the grate bridge being lowered on the sides. I usually rush to the sides and throw a seeker across the grates to kill any enemies coming around from the alley.
