If you move yes. I’m able to have the same dps (which mean same amount of hit) if I don’t move.
320% is enough when you have more than 50% chance to make a critical strike and if you have enough critical attack.
Anyway, if you really do less damages than Fletcher against world boss, you will do more damages if they fix fps issues… a day. But they are only better at single target in this weird case.
Fletcher 3 is a C7 class. On your QS3, at C5, you can have another circle of Archer > better DPS than Fletcher C3 in any way. With a Chronomancer it’s really funny . And if you take A3, so at C6, you are a monster DPS against single target. Something you can’t do with Fletcher.
