Incinerate doesnt work with Pyromantic Pact

I just got Pyromantic Pact which changes my Mana into Infernal Flame, now I cant cast Incinerate anymore, because it needs me to spend mana????

Yeah they ruined this skill.

Imagine picking a Pyromancer class that has a "Pyromantic Pact" passive which locks you out of a Flamethrower skill. LMAO.

It's harder to botch it this bad than to actually fix it.

PP ascendancy node and the Incinerate skill cannot work together. Due to Incinerate requiring mana used as fuel and PP replaces mana with Infernal Flame. PP makes Incinerate a dead skill. As Incinerate is one of the main fire skill(and coolest) for an pure fire mage build this seems more of an design oversight then a design philosophy. Please fix this as soon as possible so that I can enjoy this patch to the fullest. I play for only making fantasy build and will never play the meta. I am going a pure fire build and this is my main skill for dps beside flame blast. Please let me play my non meta build and enjoy it.
