Honestly I hate rolling Arowana Mall when I'm using charger; it has a lot of high ground but it can be very difficult to actually hit someone. If you're trying to snipe someone down below, they can just hug a wall and you can't do anything to them. I actually think the chargers are best on Saltspray Rig and whatever the new Port stage is. On Saltspray Rig there's a couple places with high ground that face the same problems as Arowana Mall, but some of them are right by a major choke point (the entrance to the upper area from the side hallways). It's also easy to defend the lower area as a charger; your blasts (with Splat Charger) have just enough range to hit directly across from the upper paths leading to them, you have a lot of room to kill from below, and the relative lack of obstacles makes emergency close-range combat easier than in tighter spaces. The Port stage, on the other hand, is just a bunch of really long hallways. You can actually cover ground. It's so satisfying.
Chargers are obviously the worst weapon in terms of point gain, but they're really valuable for guarding key areas like the midfield in Urchin Underpass or the tower on Blackbelly Skatepark (which is incidentally a very risky spot for a charger, as it has high traffic). They actually have some use in Walleye Warehouse, which is for the most part a very flat stage, meaning you don't have to make awkward vertical adjustments with the motion controls to splatter a bunch of people.
Quick shoutout to the Kelp Splat Charger for having the Sprinkler, which is great for inking out-of-the-way spots (and is a nice way to maintain an advantage in ranked battle!).
I got a 6:3 kill ratio in a game last night against Haruno; that's the best I can remember by that measure alone. Two of each were him. Of course, Splatoon doesn't record those stats :(
