Ok so I just got a hunting blade, and with that i use my faust, Heavy pulsar, or swift flourish. My damage is now very very low. I stopped using hunting blade and it's still low, I used to be about 2-5k damage. So my questions are:
1. How does damage work?
2. Which combination of those four swords and gun should I use to be best?
3. Something else here.
Everytime you hit an enemy with something that damages them, you get damage.
Lockdown tiers are based on your highest * gear equipped/in a loadout marked for pvp. That weapon set means you'll do decent in T2, with only the swift flourish as your weapon. On the otherhand, if you play T3, faust is the one with better damage output. You can still use the flourish in T3, but your damage will depend on your skill.
With that weapon loadout, I'm assuming you play T3? T3 is challenging for those not used to it. My advice is to buy a dusker set, equip the swift flourish and nothing else. Practice with the classes and pick the one that suits you.
