Regarding orb abilities

[Blake]

I noticed recently that some orb abilities such as orb of lighting (New) and Item attack black arrow bonus can be used to set-up bash-like abilities which gives a chance that a spell will be cast upon an attack. However I soon noticed that the only way this worked was if you actually clicked on the enemy unit you want your unit to attack rather than having your unit auto-acquire the target unit. Meaning that unless you actually give a unit the command to attack a selected enemy unit this chance ability will never fire, I was wonder if there was any way to change this so that orb abilities have a chance of firing regardless of whether the unit being attacked is auto-acquired or user selected...

This is one of my pet peeves. IIRC Blizzard introduced this bug in patch 1.17 about four years ago. I sent them an email with a replay, and several others on the battle.net forums have pointed it out, but Blizzard still refuses to fix or even acknowledge it. 

I'm quite certain there's no way to fix it without triggers, and the best solution requires a complicated setup to get damage events for all units.

Edit: It works if you attack-move, but of course that doesn't help with towers or wards.
