Because he’s spending most of time studying magic, not training to mastery rather than mere proficiency with a staff.They are not by any stretch, in fact full casters get fewer "unique" features. When it comes to class features martials have substantially more unique features already than full casters do, and still would even if everyone got a weapon mastery.
Full casters get more spells than non full-casters but full casters aren't the only classes that get spells by any stretch and spells are not "unique" to full casters. In fact even when looking at spells specifically, and Paladins and Rangers have more fenced and "unique" spell options than any other classes. When it comes to spells, what full casters have that martials don't is more spells and that is what I propose here. Martials would have more weapon masteries.
I am fine with martials getting extra weapon and armor proficiencies and all the unique class features that they get (which are much more than full casters). Where it starts to break down for me is weapon mastery and to a lessor extent fighting styles. If those things are in the game I think they should be available to anyone using a weapon who is proficient with it. They should not be fenced behind feats or multiclassing IMO.
My Wizard is proficient in a staff, has the same proficiency bonus to attack rolls, so why can't he learn to use it as well and do the things with it a Fighter or Ranger could do with it?
Look, I think the first thing to consider is class balance, and everyone here but you seems to agree that adding mastery to full casters is unbalancing.
Secondly, I think counting “unique features” is meaningless. How do you stack a few unique features against a full range of spells that allow far more customization and flexibility?
I know you love optimizing and prefer playing full casters. I think your biases are pretty clear on this issue.
Edit: also, I think arguing that one mastery is not that great compared to multiple is pretty facetious. Most martials do almost all of their fighting with one or at most two weapons, and your hex blade certainly doesn’t want more than one anyway.
