Can't destroy barrels and objects with one hand weapon?!

I’ve noticed this since I returned to the game one month into Season 4. My necro has been wielding a one-hand weapon and a focus, and when I target barrels, containers, etc., my toon is swinging but not damaging the object, nor would my minions attack the object. This happens to any one-hand weapon I wield. I’d have to cast a spell like Blight to the container to destroy it and for my minions to react.

Has anybody noticed this problem?

I think it happens when a certain type of skill is slotted in the slot for left click. That slot is special because it is coded to be able to auto-select what action to perform, you can turn off that feature in options.

I think when I put Blight in that slot, something similar to what you describe happens to me as well.
