I suspect this will just be another case of a hidden requirement that is poorly described - but here go. I am on the blue solstice set and the hunter strides say that I need to defeat enemies in strikes with the strike daily singe (which shows as solar when I load a strike. So I equip a solar subclass and two solar weapons - run a strike, defeat plenary of enemies with solar on a solar singe day - and no progress on the strides. What’s the scoop?
