Knight

Overview
Knight is a frontliner who passively buffs the defense of nearby allied minions. That makes it well-suited for both Top and Support roles. On top of that, Knight got decent power, defense, mobility, and CC. All of that versatility makes it a great early pick during the drafting phase.

However, the versatility comes at the cost of not specializing in any area in particular. As a result, a team that wants a specialized composition would usually opt for other classes.

A common belief is that Knight is the class that's primarily responsible for Warrior not being a meta class. Knight's Shield Bash is more versatile than Warrior's Fearless Charge and that plays a big role on higher levels of play, where players can squeeze out the maximum from each class's potential. While Warrior does have some advantages when it comes to offense, they're generally not enough to make Warrior a preferable pick over Knight.

In the Novel
When Yuel played 1v1 against the pro player Ignis, he picked Knight because it was a versatile safe choice. Ignis counter-picked him with Warrior, which Yuel didn't think of as a counter at first.

During the match, he learned that the range of Warrior's two-handed sword is slightly superior to that of Knight's one-handed sword. It was a difference of about half a step and should've been negligible in practice in melee combat. Nevertheless, Ignis used this small advantage to great effect to make Yuel whiff attacks.
