This is something I don’t agree with. Skill/Experience (both are interchangeable) is a very important aspect that determines how deadly you are as a psi. Power and will are the other two aspects.
The most prime example is the conversation comparing Rachel to Emma Frost. It’s also why Xavier isn’t left out in the dust completely by Jean’s overall power as an Omega. Again, it’s also scans like these for why Emma is basically the poster girl of skill
The Phoenix Force itself even attests to this idea that skill is so much of an important aspect that Xavier’s confrontation with Dark Phoenix ended with his victory by a combination of Jean Grey’s assistance and his own skill.
Skill is very much measurable. It is in equal parts what makes someone like Xavier, Betsy, or Emma an omega class telepath, which are the top class of telepaths with a combination of power and skill that puts them at the top of all telepaths on the planet. Jean Grey and Rachel are also in this class category.
That is not what the quote means. I can own a sledgehammer and not have need to destroy an entire household with it. It is a tool, when expertly used, can be used to effectively drive a nail or stake into the ground to build a tent as it could tear down a wall.
You are taking the idea of a sledgehammer in the most absolute sense. Like I said, the quote isn’t meant to be taken in the most absolute sense. It’s just attesting to the field Jean is unmatched in.
I think I have done a good job demonstrating so far that Jean is more than her power, as Emma is more than her skill. You don’t have to use the quote or agree with me. Most of all, you have no need to worry about perpetuating a stupid idea of Jean Grey not having any skill. Trust me as Jean Grey fan and psychic fan.
But I think your worry over my explanation is unfounded. Remember that I had a hand in creating Jean’s, Emma’s, Xavier’s, and almost every other telepsth’s RT on Comicvine, showing all of their skill based capabilities as well as their power based. Not just Jean’s raw power. Not just Emma’s pure skill.
Nor does my explanation point to the idea that raw power is all Jean had. Newcomers who have conversed with me have found themselves not only learning about Jean’s power based capability, but skill-based capability to the point where they mostly agree Jean’s superiority even over Xavier with the collectiveness of her power AND skill.
My notions only tears down the idea that Emma and Jean are one facet. Not the other way around.
