While attempting to complete the steps for the blue hood on the Warlock, the description says that by defeating enemies with the designated subclass in the strike playlist this will add progress. I've already been through two strikes and so far have made zero progress on this step. With the modifier being solar this week, I've been using my solar subclass. I've tried using two different solar classes. I've punched enemies. I've killed enemies with solar weapons and grenades. Having unleashed solar supers as well nothing has made a dent thus far. What am I missing here?
