I'm somewhat concerned about "Elemental Blast like a Cantrip"... not exactly full of confidence about it's powers.

I don't really get the argument here, I feel like the proposal's solution does solve the "at-will" problem very well.

Elemental Charges can be accumulated by spending actions, or using your blasts effectively/aiming for critical targets. These empower your Auras, and fuel your Overflows. Charge Maximum being keyed to CON makes it being Kineticist's Key Score feel a bit more rewarding, and presents an interesting decision, you can ignore it to focus on the physical stats, if you prefer Blasts to Overflows, or focus on it and your mental stats, with the Kinet's higher base proficiency acting as a buffer so that you don't get stuck with unworkable accuracy for it.

Elemental Blasts act as high-accuracy, at-will, targeted uses of elemental power. They have less direct damage than what a Fighter or Gunslinger can do, but they're more varied in what they can be used for, with feats allowing for adding additional or alternative on-hit effects, like the Infusion system of 1e Kineticist.

Overflows requiring a number of charges provides an useful balancing tool, a Kineticist that wants to go for them can spend their actions Gathering to get there quickly, while a more blast-heavy one might build them up while fighting, at a slower rate, and focus on Overflows that can be situationally useful, like healing, or emergency defenses, instead of "must casts". By depending on Charge count, Paizo can shift their action counts from the Activity into the accumulation, while still balancing them with the idea that they're a proper strategic investment.

With this system, you can have it all, enjoyable blasting, powerful "at-will" abilities that interact with your elemental choices, and as for utility... well, Adapt Element looks so far like there's some internal debate into how much Kineticist can use their powers for exploration purposes, and they've gone with "negligible for a third of the game, and no larger than the rough size of a waffle iron" so... who knows?

It's a little bit like the fighter and the monk in that the "subclasses" are designated almost entirely by the feats you choose. Currently there's not a lot that differentiates the different elements aside from the feats. That's got some merit to it but I hope they flesh out the elements to be more like subclasses instead of how fighters and monks work.

I vehemently disagree, I believe Fighter/Monk style "class diversification via feats" is the strongest point for 2e, and all classes would be better for having more of it. Kineticist itself could simply make the levels where you get an additional gate grant an extra class feat, that can be used for an "Extra Element" Feat or an additional Feat for your current elements of choice.
