Hammer Profession - Guardian or Warrior
I must admit I havent tried with the warrior but do see a fair share of them walking around. Guardian hammer however I’ve played a lot and its never seemed too good for PvE solo, it seems geared more towards a semi-support role
Both hammers are pretty good, but for pure damage you’d better go for warrior. War hammer is a lot more smooth, and has a few nice conditions too. By comparison, guardian’s hammer is more support-ish kuje Tral said, with more control skills than actual damage (though skill#2 is beast). The autoattack with guardian hammer is really kitten annoying to use also, though it’s not horrible.
