I think she may be powerful in her own right, just not when it comes to dark magic. Like Rumple said, he (dark magic) doesn't mix with fairy magic. Which is why I guess, Blue wouldn't be able to un-puppet Gepetto's parents. I think they more or less sidelined her, like they do with Rumple and sometimes Regina, to not have them autosolve the plot.

Any powerful magic being, from Rumple to Emma to Blue, can have their shadows ripped or absorbed into the hat. Also, she was able to perfom a spell similar to squid ink on Regina before with just normal fairy dust. Much of the fairies, we don't know. We don't really know what they use pixiedust for since they always seem to use fairy dust.

Maybe as magic was decreasing or dying (which I firmly believe since "last" magic bean, giant, enchanted tree, etc.), she was weakened. Though, I'm sure if they need a deus ex machine, she'll be there in a flash, haha like for August.

Note: Apparently she make people immortal too, which Rumple couldn't or refused to do for Smee. The only one to do that so far is the Sorceror.
