Its known they vanish when you get close to an obstacle/wall OR UNEVEN GROUND, you cant use those hammers at the side of a hill since they dont adapt the ground! And Anet seemed to confirm this is a wanted feature. But seriously, theres no other skill just vanishing when close to an object. I cant even use this kitten skill in narrow passages, what the hell is this. Try to defend EB OL keep at the stairways and cant use it? Well thanks alot!
Bug No.2:
The hammers dont crit, its not specified they cant.
Cant you atleast try to make Jalis a mediocre legend for out-of-blob fights by simply unbugging it?
