Suggestion on Meta energy gain

While i believe it was needed to be nerfed, outright destroying the gems to unplayable levels isnt great considering theres ascendency nodes and skill tree passives people can invest in for energy gain.

I know the issue is stemming from stuff like eye of winter proccing gems way too often

My suggestion is this:

Keep energy at 100 base, scale with cast time adding 10 per.1 sec as original

HOWEVER: PUT A COOLDOWN ON ENERGY GAIN PROCS. you can easily put the cooldown to .5 or 1 second where no energy can be gained on that gem until its over.
This will allow energy gain to scale off mob values in a meaningful way
10 for white mobs
15 for uncommon
20 for rare
25 for boss

Clearing wouldnt feel like a complete slosh when people are speccing into meta gems and still get procs every so often while allowing that boss feeling you were going for to do more meaningful damage, sure this wont fix small low cost spam but it would fix infinite loop issues and allow melee builds and attack speed builds to still get what they want out of the gems.

It would easily prevent the comet spam where people are chaingunning comets off freeze or crit.im not sure why this wasnt put into consideration over the current solution. Also the comet having a base energy of 300 seems bugged and intentionally nerfed to push people away from using it by doubling the energy cost for no reason
