Suggested Change for Invocation Meta Gems!

Hi! I had an idea while waking up this morning about Invocations, and I'd like to share to see what y'all think!

So. Currently, it seems like the Cast-On Meta Gems are always going to be good so long as they don't get any total overhauls. I don't forsee them getting any, considering the amount of hoops you have to jump thru to get the most endgame automation setups, but I could be totally wrong!

The reason I bring this up is because right now, Invocations kinda feel like a cool idea growing in the wrong place. The hoop that you have to jump through (pressing another button) feels... redundant, given that the Cast-Ons are automatic, and now we even have Spell Echo to work with!

So, my proposed change is this; remove them from the Spirit Gem pool, and make them Support Gems that only work with the Cast-On Gems.

For instance, Barrier Invocation. It would instead build additional Energy for the Cast-On Gem it's Supporting when your Energy Shield gets hit! I'm not sure whether the trade-off of losing a Support Gem slot would be a strong enough downside, but I'm leaning toward "yes".

Feral Invocation could be changed to build additional Energy when using Shapeshifted Attacks, Elemental Invocation could build additional Energy when consuming Infusions (since Cast on EA already builds on Ailments), etc etc.

And fuck it, here's some of my own ideas;
Ambrosia Invocation - Gain additional Energy when another Skill uses your Mana Flask Charges.
Torturer's Invocation - Gain additional Energy when another Skill extracts an Impale (once every .2s, maybe).
Deflecting Invocation - Gain additional Energy when your Deflection procs, once every .2s (sure, why not).

I think that this would be more interesting than Boundless Energy I & II, which just give flat bonuses to Energy production. Hell, they could even give MORE Energy gain than Boundless Energy if you can only equip one of them p/Cast-On Gem. Since you have to jump through a more specific hoop to get it, I think that'd be a worthy trade-off.

Ritual Cadence is the only hanger-on of this mechanic that I have no idea what to do with. Delete it? Rework it to apply to Cast-On Gems?? Who knows!

Thanks for reading!

Oooohhh, so you're making an Energy boost support gems with current Invocation effects to work with Cast On Gems.
That's cool!
They could make these into Lineage support gems.

Totally! I could see there being some rad Lineage supports based on it!!
Reaper's Invocation in particular seems like it'd be a bit too powerful to be a normal Support Gem using this concept, so maybe it'd make for a good one!!
