I guess control of the elements is a powerful thing, but correct me if I am wrong, her power seems to make her tired fast... it seems as though she controls a whirlwind and then has to take a break... plus unlike Wonder Woman she could probably be injured easily since she has no major defenses against serious blows.
For DC I agree with JB on Wonder Woman. All his points seem valid enough for me.
Lets not bring Marvel here because their Heros are differant than DC Heros. If I were to rant on about the differance I would be off topic so I wont.
