Define what difficulty means in this context.
Would an easy mode give the enemies lower health? Buff the player's damage/decrease incoming damage? Increase I-Frames for the player? Stamina is not affected by armor?
Its the same questions you have to answer when instituting a higher difficulty mode. Do you just decrease player damage or increase enemy health? Make AI smarter/more prone to mixing up their movesets? Fallen Order is in the broader Soulslike take but it makes parries more difficult, makes enemies more aggresive and increases damage taken.
Finding a balanced difficulty that remains challenging and fair within the confines of the difficulty of the gameplay is difficult.
The name is wackyteen for a reason.
Never doubt.
