Maybe they should make a valk weapon that provides a proc chance on soullink with every attack?
If it's high enough it would be equivalent to having that item and removes the need to carry around an extra item, taking up weight capacity(if they would decide to make it not have 0 weight).
Or put the active soullink skill on the weapon, then they will be in a similar spot as sinx having to refresh their main buff every couple of minutes.
On another note an active item to reset hatred would be a good buff to the class. Not sure though if having hatred on basically all classes without the need to visit a npc would be op though.
