Herald of Ash cannot be supported with -on ignite supports

Herald of Ash's tooltip very clearly states that it ignites enemies with the explosion, however support skills that interact with ignite such as ignite chance, ignite magnitude, or explode on death if ignited by skill cannot be slotted into the Herald of Ash spirit gem.

Herald of Ash can only be supported as if it were a standalone aura. Only supports that attach to auras work with it, such as Clarity or Vitality.

Yeah, I am so confused by the support choices for this skill. The choices that you can and can't choose seem to contradict each other regarding how this skill is supposed to function.

Apparently, you can't use Ignition or Searing Flame, because the explosion that inflicts the Ignite doesn't actually hit anything. Not sure how that's possible.

I'm guessing the reason you can't use Fiery Death is because it doesn't have the spell tag, even though the support gem just says, "a skill", not "a spell".

Then there are supports that clearly shouldn't work with this skill, that are on the list of skills that apparently are supposed to work with it somehow.

First there's Brutality, which increases Physical Damage, but HoA's explosion doesn't DO any physical damage and Ignite certainly doesn't.

Then you have Swift Affliction, which only affects NON-Ailment damage over time, but HoA only does Ignite, which IS an Ailment Damage Over Time effect.

Then you have Concentrated Effect, which increases Area Damage, but HoA doesn't DO Area Damage, it inflicts ignite without hitting anything apparently. If it DID do Area Damage, then it would be "hitting" in which case the other ignite related skills would apply to it.

Then it has Minion Pact on the list, which clearly says "Supports damaging skills you use yourself" which again, HoA is not. It is a triggered effect based on Overkilling a monster.

Then there's Fast Forward, which lowers the skill duration, which I assume is meant to lower the duration of the ignite? But that doesn't make the Ignite do its damage faster, it would just make it last 30% less long. The skill itself doesn't otherwise HAVE a duration. It's a Persistent Buff Aura

None of this makes any sense whatsoever. I can only assume this is an enormous series of bugs, but I don't see why there aren't more reports about this, and how it could have been missed with all the patches that have been put out recently.

I'm so confused.

Hopefully this is fixed next patch? Devs?
