Maybe this have been answered before but I want to know if this class is just spam RMB and LMB only (not saying is bad) and have high dps. I currently main a Warden but Im struggling with some daily bosses while I see all this ranged just getting stunned some times... Should I reroll gunner or stay Warden? Im mostly doing solo to grind for my gear. Also willing to go FM. So maybe I can get some guidance on the class?
