Not even Monk. Hm....Yeah, Monk and Battlemaster aren't what I'd regard as being complex. They tend to have a best action for their uses of ki points/maneuvers - and the only real way around that is to burn them faster.
That's sounding more like PF, where you get CMB & CMD so your fighter actually can get particularly good at combat options. Can't see anything like that in 5e, it'd break Bounded Accuracy to pieces.A Battlemaster who could use a maneuver every round of every combat might get interesting - do a different one each round and have more chance of success - keep repeating a maneuver and have less chance might get interesting. So try to keep tripping someone and you're better than someone untrained in doing so, but on the 2nd attempt, the other guy might have advantage on the saving throw.
Having a menu of maneuvers - combat tricks - that get less effective or harder to pull off isn't a bad idea, but it does come with some bookkeeping overhead (but you /want/ complexity, so there you go).
How else would this hypothetical class differ from fighter? Still durable? Still multi-attacking for high DPR?
