User blog comment:FairyTailFan/Juvia not as strong/@comment-5170433-20130606234005

In the GMG Lucy didn't have as much magic power as Juvia, it was Aquarius that did. Juvia and Chelia having equal power made sense. Juvia overpowered Meredy because she threatened to kill Gray. It is true we haven't seen any change but I'm guessing her current power is equal to the power of Pre-timeskip Erza.
