I've read the through the rules, but because there are so many tweaks, some very subtle, and no summary of differences it's kind of hard to easily digest the implications. Sort of the point of the OP!
But in this case, I was more hoping for people that understand this issue in O5e and were also playtesters or people that have gotten a chance to play LU extensively since release (exist?) to comment on how this balance feels in games that have 1-2 combats a day vs. say 6-8 and various short rests.
I don't think this can easily be inferred by just reading the rules because it kinda depends on the expectations of how many short rests between encounters are expected when designing the power level of the manuvers for instance. I'm not knocking LU as a whole as it has a lot going for it, but my hypothesis is that LU has not addressed this particular issue.
It'd be nice if someone could just say " Yeah, LU doesn't solve that. If that was a problem for you in o5e you'll have to fix it in LU as well". Or "Manuver classes were balanced around using 1 exersion a fight and anything more is gravy so short rests are nice but not really required." (I doubt this is true but just an example) You seem to be addressing a completely different issue in your responses.
I am hoping to play myself but having the main differences both in major rules and their main implications on play would go a long way toward convincing people I play with to adopt LU in the first place. And, for instance, if I know that this hasn't been solved, I don't have to waste time playing in a way I know I won't like. Hence I think the value of this thread for many of us.
