Design Notes
Theses variant are inspired by the Rogue being a martial class without Extra Attack. As such, multiclassing Rogue + another martial often provides a good synergy and you have more freedom on the lvl split without the wasted feature at 5th.
Also, Extra Attack is strong but boring and flavorless.
