Question to Sunder and Armour Break

Hi,

wanted to do a combination of Warbringer Armour Break passives + Sunder, but after getting to that point had to notice:

It does not work!

While I´m a bit disppointed now I´m fine with it BUT:

Sunder Skill description should clearly state that the skill itself CAN´T break Armour. Neither with the Warbringer passive nor with the "Splinter" support gem.

WHich rbings another point:

Why can you even slot "Splinter" into Sunder, if it does not work?

Bug? Missed infomration? Do I mess up something?

Happy for input on this...and ideas what to do with my 32 Warbringer xD

Cheers!

Use a different skill to break armor, then Sunder to consume and crit.

Armor Breaker either self-cast early or with Ancestral Warrior totems once unlocked. The totem + Sunder version is what I'm running for bosses/rares in maps.
