That is true but WI causes slow after rapid precision hits which intrinsicly stuns overloads so it's probably just an unintended thing they never had to address before. Last time I think we had antibarrier scout was season of the plunder.

it would say on the weapon or a perk that is has intrinsic champion mod and it doesn't. yes it has slow and freeze which both do overload and unstoppable but no where on the weapon does it say that it has an outright champion mod. plus the weapon can do barrier while radiant. so it doesn't make sense why the barrier mod doesn't work with it.
