As of this writing, I'm a Lv. 50 Fo/75 Br. I started as a Braver primarily because of the speed the class, but I've been trying to play as a proper Force while doing Marlu's(Massively underrated waifu BTW) Orders. My playstayle has always been "Gotta go Fast", so charging every Technique feels tedious. However, there is a Rapid Casting perk for Fire Techs that I originally got just for casting Shifta. All of the other elements take longer to charge, especially Light Techs in my experience. I've also haven't seen large increases in damage when exploiting enemy elemental weaknesses; 1-3K more, at best.
tl;dr I'm impatient. Can I just set everything on fire?
