Exactly.
You can literally use a magic high jump to escape petrified/frozen instantly, and some magics simply require charging your magic energy for a second to unstuck you. Whereas if you’re paralyzed, you’re screwed.
Here’s the thing: You’re biased in favor of making lighting more op than it already is. It will be even more overpowered when lighting users get their second magic water and third magic ice. When players a frozen, ligthing gets a 1.5X damage boost. That’ll help make lighting get its paralyze effect. The paralyze effect cannot be broken out of no matter what, unlike the frozen and petrified effects. Your idea is completely ridiculous. The paralyze effect is kind of an end game thing, not an early game thing.
