Lets talk about how Scarlett Witch is powerful enough to simultaneously destroy an infinity stone/kill Vision, and hold back Thanos (who has all the other stones)......yet needs Cap and Black Widow to save her ass earlier in the movie from a couple scrub black order goons. Legit

All of her power is in using energy.  She's not nearly as good with someone in her face, especially if they take her by surprise.  Cap and Black Widow, on the other hand, are at their best when someone is up in their face.  Scarlett Witch is basically a glass cannon.
