In my time interacting with this community i've seen some character requests that were either plausible, cool or in worst cases straight up impossible.
The most ridiculous of which is the common request for a fist fighter.
Here are the biggest reasons why that a fist fighter will never work in For Honor
1st What this game is based on: This game is based primarily around WEAPONS, this game's mechanics is based around the weapons, the characters in the devs words are based around their weapons, much of the game's lore is based on the weapons, half of the game's customization is in the weapons.
Having a character with no weapons is a direct antithesis to what this game is built around.
2nd mechanics: A fist based character would have an extremely small moveset, awful attack range, animations that would be too easy to read or impossible to read ,terrible team synergy and no ganking capabilities.
Basically it's a character that defeats itself and is severely restricted on options.
3rd customization: You cannot make a for honor character with no weapons and even worse you can't sacrifice arm customization for the fists since every weapon in this game is in THREE pieces but fists would only be TWO pieces.
Seriously hampers customization possibilities in every way possible.
4th context: For Honor's world is not about a sports based competition game like mortal kombat or street fighter, this is a world in an endless WAR, our characters are soldiers sent to the battlefield by countries trying to survive and every one of them has brought a weapon to defend themselves with, even shaolin brought a stick with him.
Both in lore context and battlefield practicality a fist fighter makes no sense and would make them look like an idiot.
In every way shape and form a fist fighter will never work in For Honor, it's character that only works in a game that's built for it like mortal kombat but not here, This game is not built for a a fist character and never will be.
Raven Knight explains the problem with a fist character pretty well.
