Yes I'm sure. Hit your shots and think smart, and you don't need any ink management abilities (Ink Saver Main, Ink Saver Sub, Ink Recovery Up) on any charger. Often I see lower skilled chargers running a bunch of Ink Saver Main and it's just a crutch for missing shots or painting more which are habits that you're gonna wanna break the better you get. Instead of compensating for skill with abilities, just learn how to play the weapon with no crutches, and you're more free to use more effective (or broken) abilities to maximum potential.
For Hero Charger, Firefin, and Kensa charger,
this is my build.
For E-Liter 4K Scope,
this is my build.
To answer any questions, no I don't run Tenacity. It's really not that effective.
Quick Super Jump is a must have for jumping out of bad situations. I always make sure I have 2 subs.
I run Haunt. I like it personally and it's good for callouts in competitive.
Lots of swim because I wanna be mobile and reposition fast. Also I can go further distances with charge holds.
Special Saver if I need special quicker after respawning.
One sub bomb defense because it's flexible in it's uses. Namely, my team runs Ink Armor all the time so I want to be protected from bomb indirects.
