Storm's powers affect a lot more than the person she's aiming at. Wind, lightning, rain, temperature, all of that can change the entire fight. She can move people, protect them or make an area almost impossible for the enemy to operate in. But her emotions can affect the weather too. That gives her a reason to keep herself under control even when she's angry or frightened. The calm way she carries herself early on has something practical behind it. Then Cyclops leaves after Jean's death, and Storm takes over leading the X-Men. Now she has to manage the rest of them as well as herself. That's a hell of a group to take responsibility for. Wolverine has his own ideas about almost everything. Kitty is still a kid. The next emergency might involve aliens, a supervillain or somebody trying to kill them for being mutants. Storm grows into that job by making decisions while all of it is happening. Nobody gives her a peaceful stretch to get used to being in charge.
