The firing range is so so so so so important. I promise everyone it's not a waste of time. For charger I do all of
these. The super important ones for me are the bamboozler one and the squiffer one where you just put yourself amidst all the moving dummies and just move around and shoot them at different angles and snapping. That one goes for all weapons really. Sometimes I'll end up spending quite a bit of time just sub-strafing and shooting them to practice that. Also good for practicing readjusting your aim at different angles for blasters, sloshers, shooters, nozzlenoses, dualies, literally every weapon class. I also practice snapping with chargers and blasters and practicing 180s and confusing movement. This helps to practice close and personal 1v1 situations where you shoot once, move, shoot once, etc. until they die (this goes for blasters or charger partial shots). I usually don't go into ranked until I'm feeling really good about my aim - otherwise I miss some really stupid easy kill opportunities. Basically, I could do stuff like this for hours and not get bored.
I also really enjoy practicing turns and 180s and 90s and back and forth and all that stuff on the rapid blaster. It's fun. Also helps with these semi-okay clips
Also important snapping up to the higher targets from ground level and getting used to that sort of thing so you can consistently shut down splashdowns.
Also, when I first learned how to use inkjet, I just threw on a bunch of special charge and painted for special and practiced getting used to aiming with the bullet velocity on the moving dummies and then reset and repeat over and over to get good at it. Reason being you really don't get that many opportunities to practice inkjet in battle if you don't know how to use it at all yet.
Yeah anyways I love the firing range.
