Could that have been the reason for the Ronin class > Assassin / Samurai job ideas in the past.
Joking, but yes, there are similarities, apart from your Samurai here not necessarily having any general stack or charge system that would carry over between different pre-finisher choices (if I recall correctly... maybe that was only WoW's rogue, and then half of all rogue builds since).
That said, I wonder why there aren't more ready examples, as it's still a incredibly general design philosophy to center class gameplay on, and effectively differing from true rotations only in flexibility and greater control of dynamics/output peaks and troughs.
