It just doesn't seem to really fit into the power scale of any medium. Generally when you have a character that can copy another persons (like Rogue from X-men, Leech from Superman, or Peter from Heroes), you run into two different versions of this ability:
 * 1) Either the person can only hold onto the power for a limited time before they have to "recharge" or
 * 2) They can hold onto a power as long as they want.

However with Number 2, the characters will eventually loose all control of their abilities at some point and will ultimately die from some kind of power overdose. Number 1 seems way more likely to appear in this series or you would end up with a massively OP character in the show.

I still convinced that she is just a skilled Glyph-User in the field of Fire based abilities. I can understand that maybe Fire is her favorite if she can copy other abilities, but during her fight with Glynda she never changes tactics despite the various forms of attacks Glynda uses. Plus if she is a Glyph-User anyway, they have been shown to use a wide range of attacks (Weiss can use ice, dash, and fire); making the need to copy abilities kind of redundant.
