Burning Frenzy

[-Variant]

Hi. It's me again. I'm back.

I'm still under the impression this skill may be better if it were modified just an ounce.
I'm trying to give it a go again but it's so specific and I'm really struggling to find many opportunities where I'd want to use it.

A good portion of the bosses where I'd want to use it seem to be entirely immune to fire. I'm looking at you, Daywalker and CC.
There's not a lot of enemies that both have enough health and can be set on fire that I encounter constantly that'd make me want to use the spell. 
It being an entirely combat focused skill with a requirement that a portion of the mobs in the game can't fulfill feels very off.

I still feel like this skill could benefit from more uses/opportunities.
I've seen a lot of proposals for this skill, but instead of repeating them all I'm touching ground to see what others feel.

honestly i kinda wish firefighter, along with its current effect, let us set normally fireproof enemies on fire

like they won't panic or take dot, but they're still on fire so at the very least you can use burning frenzy on them and get embers too i guess
