Armor Explosion(& HoA) doesn't work with Shockwave & Warrior Totems. Description issue or intended?

I am not sure which is the intended outcome or if something broke when the chain explosion thing got patched.

Testing if Shockwave totems would work with Armour Explosion on my Warbringer and sadly it doesn't. The real issue though is with the clarity of some of the description of skills & supports.

The lines that made me thought they should work together:
Shockwave totems says its an "attack" skill and armour explosion says supports attacks, causing them to trigger a fiery explosion when they fully break an enemy's armour.

After testing and finding it out doesn't work I try to find out why:
Moused over attack description and it says Attacks are skills that directly use YOUR equipped weapon to damage enemies. So I thought, ok totems don't use my weapons and therefore these kind of supports may not work.

Then I became confused when I checked the skills tree:
Nodes like Attack Area Damage and Area, which explicitly states increased Attack Area Damage and increased Area of Effect for "Attacks" with the same definition above, affects the damage and aoe of shockwave totems.
