Although the X-Men does much better with the powers as part of individual identity/culture thing than Flash's random assortment of metahumans, I cared about Frost and what happened to her. She was acting responsibly while the others were being idiots. I'm glad it didn't turn out Kramer was gunning for metas because she had a personal vendetta against Frost, it made her reasoning more sound.
I'm not sure we need to see Frost again after this, but if the story calls for it and there's a good reason, that'll be okay too.
I'm wondering if bringing brought down to earth/having to live in the physical world means the Speed Force is starting to become more flawed and human. That tends to happen when gods or beings from a higher plane lose their godhood and become concerned with petty human matters. I did love Barry and Flash trying to help Fuerza as best he could, despite making things much worse.
