The battle master is among the best fighter sub classes for sure, but far from the best subclass in the game. I will not repeat my reply up here, so see below in this post:To me this seems like a false dichotomy. Battle masters are widely regarded as one of the best sub-classes in 5e, and are highly effective at all levels. They definitely play nothing like wizards, but they are a very popular choice and every party is happy to have one.
And their maneuvers do scale, because they are designed to offer situational advantages to abilities that scale. For example, when you use maneuver dice to grab the rogue an off-turn attack, a pretty classic BM maneuver, the rogue gets an extra sneak attack. Which scales. When you grant your ally advantage on their next attack, that scales. And so on.
That's exactly what I mean! The fighter scales based on number of attacks and attack power. That's why I mentioned that they had good attack scaling. That is not what the Warlord is about, though.Don't maneuvers and weapon masteries automatically scale as Fighters get higher level and get more attacks? The multiple attacks are the power increase. The maneuvers and masteries are the tactical option increase.
The fighter gets more attacks, but their maneuvers don't individually improve. The scaling of maneuvers is 100% about how the number of attacks scale.
It is the case that some maneuvers improve opportunistically thanks to a secondary thing improving and the maneuver improving "by proxy". But most maneuvers are completely static.
Want to talk about something more appropriate for high level? What about a maneuver that allows everyone else in the party to move half their movement speed as a reaction without triggering opportunity attacks?
That is the kind of scaling that maneuvers currently do not support, because individual maneuvers do not improve and there are no high level maneuvers gated behind any kind of obstacle.
