Pros: - Overall great damage for fp spent - wide aoe coverage with high damage with Flame of Frenzy/Unendurable Frenzy - extremely long range high damage spell in Frenzied Burst - similar startup animations across all spells, allowing for mixups in pvp (e.g. All things being said, they're not unusable, unlike some other incantations, and they all serve their purpose. Now that the madness status effect scaling with arcane on spells has been nerfed, it's much easier to judge these spells on a more balanced spectrum without cries of 'no its broken pls nerf' clouding said judgement.
Because if channeling the volatile flames of a chaos outer god doesn't sound cool to you, I don't know what will. What they lack in viability and utility they make up for in fun factor and flavor. I'd place them overall in like a B- to C+ ranking overall, both in pve and pvp. These spells are not great, but they're definitely not bad either.
