yesThis is why 5e should have a dedication Skills and Tools chapter.
no, we need to go deeper than 3.5e with skillsNot as in depth or fiddly as 3e but each skill having 2-4 dedicated DCs and usages that ranged the entire spectrum of the base game.

and since skills do not scale +1 per level, but +1/2 per level at best, we need to move away from +5 per category DC on skills.
+3 after 10 would be a good scale
DC: 5,10,15,20,25,30,35, should go to;
DC: 5,10,13,16,19,22,25,
or having universal subclass progression and having beast master be a universal subclass.If I were to ever make a simple dungeon crawler, I always thought that I'd just have every skill have its own page of its description and the core range of usages and the associated DCs for it. This would allow me to decrease the number of classes as you could "Create a Class" by choosing a set of skills.
Then you wouldn't "need" a ranger.
You could make a Beastmaster by creating a priest and summon your companion with Nature, tame it with Animal Handling, and heal it with Medicine or Religion.
probably,You could make a Hunter by creating a fighter and getting your bonus damage with Survival, Maneuvers with Athletics, and sneaking with Stealth.
or again a universal subclass.
1st level:
proficiency in 3 skills from list: Nature, Investigation, Medicine, Animal handling, Perception, Survival, Stealth
advantage on Survival checks from tracking
3rd level:

darkvision: +60ft
+10ft movement

astral step: prof bonus per day, Bonus action teleport equal to your move speed.
14th level:

astral step is 1mile
now, this is 2 minute hatchet job at making a subclass with exploration and endurance theme.
