CO is still very expensive though in terms of Tripods. And yes 4-5 makes a huge difference.
Also while being non positional calling it a “hitmaster” class is a bit misleading since you usually dont run hitmaster. Its okayish to do but your Awakening is not affected. And the Dude packs quite a punch and you get him out often.
FI Wardancer:
Very fast and mobile, does not have to back attack, 20% damage reduction with max tripod on energy combustion, great synergies (+18% crit, 8% atk speed, 16% movement speed).
Gunlancer:
Slow but very high shield uptime with push immunity. Great synergies.
Downside for both: need many tripods to be relevant.
Any class with a recommend stats of 50:50 on Swiftness would do it.
You won’t be too slow to dodge , your skill not cooldown fast to be a piano class and your dmg is still enough to get things done.
