Am I missing something regarding Meta gems?

It just took me 5 minutes to get Cast on ignite with Impetuis to cast a Fireball. It slowly ticks up by 1%.

I gotta be missing something because this is useless. The gem doesn't say ignite magnitude affects energy gains.

It's also worth to read the blue words.

Gains 2 Energy per Power of enemies you Ignite with Hits from Skills, modified by the percentage of the enemy's Ailment Threshold the Ignite will deal

It used to simply gain 20 energy per ignite. That was changed in 0.1.0d patch

In order to make the source of the ignite matter we are making the energy gain be dependent on the strength of the ignite.

I do read. That's not exactly crystal clear. I don't know what "percentage of the enemy's ailment threshold the ignite will deal" means when ailment threshold only affects the chance to apply ignite. So, what, the energy received for ignites is based on the magnitude of the hit dealt which translates to a higher chance to ignite? And that chance to ignite is considered ailment threshold dealt? What?

Regardless, I get it. Bigger ignites, more energy, which means it's useless for fire spells unless your character is stacked for it. Fire spells just never hit hard enough to scale ignites to anything more than a sunburn.

But thanks for providing some insight when most would've just left the standard passive-aggressive snark fart. Genuinely appreciate that and I don't mean that sarcastically.
