sword vs greatsword
Both
If you want to bring a staff for the Swiftness, Greatsword is probably better as a main damage weapon.
sword has the highest auto attack damage, greatsword has wider cleave arc and its not as inconvenient as sword AA 3, WW is our strongest burst move in PVE i you can land all the hits, Leap of faith can be used without a target to approach retreat or jump over gaps, BB provides a weak yet useful crowd control and SoW is the strongest symbol we have if Im not mistaken. To obtain the best dps you will have tou use sword/focus and greatsword using Greatsword 2 and 4 and swapping to sword until they reset ( overly simplified description)
