Jean Grey manifested her mutant psychic abilities at an early age, and was subsequently sent to the Xavier School for Gifted Youngsters to learn control over her powers.Marvel Source
As a founding member of the X-Men, she's spent most of her life as a hero and has the calm confidence of a seasoned pro.
When Jean served as an avatar for the Phoenix Force, an immensely powerful entity of death and rebirth, her powers were greatly enhanced. Although she no longer operates on that scale, her telepathic and telekinetic abilities make her a formidable opponent.
The thought behind the point spread across Avatar, Corona, Rebirth, Rejuvenation and Tempest is: I tried to get the most value out of each point, since they are all useful in some way but not mandatory skills. 9 points in avatar gives me rank 10 which gives me 4 instead of 3 phoenix power each time I get hit. Rebirth with 3 points gives me 63-66% rebirth. More points in rejuv only gives me 0.1 spirit per second, and more points in tempest gives me only 0.2-0.3 seconds on tempest.
I think it is personal to see where your cutoff is for each of these skills, so I suggest to play around with it and see what works for you.
This is by no means the best or optimum Jean build, but it is the one I am having the must fun in, and it fits my active Limbo playstyle.
