Hey, play however you feel. Stormcaller is probably better for killing enemies compared to Voidwalker. More mobility and area can be covered with it. One of the reasons I love Nightstalker is for the revives. My Sealed Ahamkara Grasps makes impossible revives possible. I run into the most dangerous revive situations after going invisible, revive, and refresh my invisibility while making the revived teammate invisible with my back up smoke so we can both get back to killing.
