User blog comment:Leon Jung/I wonder if the Winx could use their old power?/@comment-4074115-20140416033415

Since there's no precedent for it, I would say that no, they can't go back.

Still, it does seem unfair that they have to lose a power in order to gain another. The Winx risked their lives to earn Enchantix and yet lost those hard-earned powers in less than a year. XD
