Glynda...I'll be honest, she has a game-breaking ability, probably Story-Breaking ability: Her "telekinesis". And that's terrible.

She can easily fight Cinder as an equal adversary, and probably even beat her without much problem in an equal fight. Along with that, she can easily move things and even enemies like a fucking Jedi Master.

As proven by Breach, this allows her to effectively make any estructural damage done by the Grimm Absolutely Null by using The Force and fixing everything in seconds. In other words, as long as she exists, any damage the villains do, literally won't last.

This also gives problems to the writers, which by themselves aren't the best anyway. What problems? Well, given how powerful Glynda has proven to be, the writers need to go further to successfully explain how someone so powerful as Glynda could be defeated (because if she's not defeated, the villain plan may as well be a dream), while also trying to avoid making it seem like she grabbed the Idiot Ball, and also, if possible, without making it seem forced, or even worse, as an Ass Pull by Miles and Kerry.

She needs to be killed at most, at least get a noticeable weakness that doesn't feel like a Hand-Wave or Informed Flaw.
