Quite a long time ago now, Revenant's Defile buff was changed to not expend a charge when attacking structures, since it has no effect on them. However, the ability still wastes a charge when attacking gadgets and wards, despite this having no effect as well. I've always found it a little annoying. Could it be changed as a quality-of-life feature?
If there is a balancing reason for this issue, please enlighten me as to what it is.
