Currently, after some patch in Season of the Splicer, Dunemarchers are not working as intended with Supers like Fist of Havoc and Sentinel Shield. During either of these two Supers, Linear Actuators doesn't proc as it should. How it should work is that if you sprint around during a Super and get the Linear Actuators buff then proceed to light attack an add or an enemy player, the Linear Actuators buff procs, resulting in the chain lightning effect, but right now if you try to do that it will not work, resulting in the chain lightning not procing, and the Linear Actuators buff will disappear from the left corner of your screen, indicating that it should have proced, but it doesn't. The only way for it to work at the moment is to get the buff then cast your Super and your first light attack will actually trigger the chain lightning, but no subsequent attack will. The only Super Dunemarchers still work fine with is Glacial Quake. Lastly, it's not the first time Dunemarchers are bugged. Last season they were bugged for quite a while as well and then got fixed. After that they were working fine but this season they broke again.
