Adding numbers is boring. It's something your class should do. Each character only has a handful of manuevers, so each of them should do something interesting. Even with the greatly lowered spells per day, casters get access to spells that do interesting things; why should the non-casters only get to toll a die and add the result to another roll?
Adding numbers doesn't have to be boring. Especially in a bounded accuracy system, where each addition is worth so much more. The problem I see developing right now is that despite their attempts (and claims) to the contrary, there are once again a lot of ways to get pluses to things, and since every mundane class so far uses expertise dice the same way for the same basic set of maneuvers, it's not all that interesting anymore. Still, it can work, but going back to what I was talking about before, each class should get to add their pluses to different things (and yes, they should also get to do unique things that aren't just straight pluses). If everyone is just rolling expertise dice and adding the result to to hit or damage, then that's what's uninteresting.
