Is it just me, or has Vintage turned into a microcosm of this election? Or is it visa versa?
Anyway, Blue decks need Misstep to fight other Blue decks, lest you get blown out by a full grip from you opponent after they go Ponder, Probe, Mox, Gush, Brainstorm on turn 3 or 4 with a Mentor and 5 Monk tokens. Probe is also an issue because perfect information tacked to a free cantrip is more powerful than most of you want to admit. Turn 1 Probe... oh, no Force? OK, gg. Probe turns a thinking man's game into a brainless format. Misstep is a necessary evil to fight that nonsense. Restrict them both and I bet Blue decks open up and can simultaneously improve the shops matchup.
