Ok since you guys nerfed xSword before instead of nerfing mercenary it is barely good on any other career so we have to take a look on other weapons. Take greatsword for example, since xSword is slower than any turtle kind i have seen in the world and literally nails your feet into ground the moment you want to do something, even when you block, why not try greatsword. But the thing is; This weapon is extremely outclassed by other weapons. I mean i have no idea why krubers greatsword even exists at this point because i can see no point in even considering using it. It is not good at horde clear, it is not good at killing elites. On the other hand you can use 2h Hammer wich has both really decent horde clear and really decent elite killing potential with light overheads and insane stagger on top of that. Heck even one-handed sword does a batter job than greatsword in any situation.
So yeah, nerf Merc, fis xSword, buff other weapons isntead. I think that should be the moral of the story.
