I like the exploration focus of LU5E, but I hate the expertise dice, I just use regular expertise instead of it.With skill specialties and expertise/hindrance dice, Level Up also has a better skill system.
Why would removing the ability to cast spells from the Ranger affect 5e's magic system as a whole? As for magic being the number one solution to any problem in D&D, it's not. The majority of problems that a party can run into during an adventure can be solved through role-playing.If you remove spellcasting from rangers, you also have to gut the magic system to make the loss worth it. Right now, magic is the number one solution to any problem in D&D. Now I don't think it should necessarily be the case, but clearly the game sets up survival and exploration as low hurdles to clear and lets you handwave it away with a couple of 1st/2nd level slots.
