Completely separate from the argument over whether or not the card is fun... From a purely strategic perspective, winning non-workshop decks right now run a lot of one drops.
If for some reason, at some point, you have decided that being Misstepped is a problem, and you started cutting one drops to avoid it, you're leaving match wins on the table.
If at some point you decided that losing a card to Misstep is worse than losing a card to Swords to Plowshares, you might be throwing away cards when Misstep isn't around.
If at some point you decided that losing a one mana spell to a zero mana spell is worse than losing a two mana spell to a one mana spell, you might be throwing away tempo when Misstep isn't around.
If you believe these things and you find yourself losing to Misstep decks a lot, there's a decent chance you're only losing because they have more Preordains than you. If you believe these things and you find yourself losing to Workshops, there's a decent chance you're not running enough one drop removal.
(On the other hand, if you've decided that Misstep is the only thing holding you back from playing Goblin Welder, chances are pretty good that Misstep is increasing your match win rate)
This is all completely separate from the argument over whether the format is more engaging with or without the card - but given that we're currently in a 4 Misstep environment, I can't help but feel that people seem very far apart on how they strategically react to the card's presence in the format.
