Dragonian (Inferno Resonator) Clarifications?

I have a few questions regarding some unclear aspects of how Dragonian works exactly, epecially in regard to Inferno Resonator.

1. What exactly are flame orbs tag-wise? Are they skills? Basic Skills? Something else entirely?

2. With the new adjustments to Dragon Sovereign of The Sun, Inferno resonator can now infinitely, passively sustain max communion regardless of the -1 communion every 30s due to the 1 mana/s gain with the perk.

A 100% increase in communion effect seems incredibly powerful, yet I haven't seen much discussion about it's usage and notice the wiki still recommends the Chaos and Order option even for this weapon. Shouldn't the 100% increase represent greater performance in theory?

3. With the major enchant nerf, is triple enchant (two flame, one darkness) still the play? I know she's more ATK based than skill-damage based (and also ties into the first question there) so it probably still is, unsure if skill-damage is actually affecting orbs directly?
