Regarding Ranger classes, Tracking and Stealth
In RPG games, stealth, cunning and specifically ambush has always been a staple of the hunter / ranger class, in some cases even more then the bow. Over the years however, the bow/ranged weapons would sort of become the identity of the ranger and what actually made a ranger, a ranger was sort of lost and oftentimes handed over to the rogue which can be a very similar class, this was undoubtedly an attempt at making the two classes more distinct so they stood out from one another.
Basically, I just want rangers to be able to stealth, it is a huge part of their class fantasy, the entire identity of a hunter is to ambush prey. And rangers also fall under this category, they often have ambush tools in RPG games, including DnD (Snare, Hail of Thorns) and even in MMO's like WoW etc. they generally have bear traps or other ambush mechanics at their disposal. Stealth is pretty big part of ambush as well, and I would hope with some combination of Ranger / Rogue or Rogue / Ranger, you could have both the tools of tracking, stealth and ambush.
Now, let's talk about tracking. Tracking mechanics can be insanely fun if it is implemented correctly, remember, my character is a master tracker, not me. I think the best / most fun tracking I have ever done has been in Apex Legends using the character Bloodhound, essentially it highlights footsteps, (Tracks) it puts a ping over where they reloaded / fired weapons (Magazines / Shell casings) a ping over where an enemy was injured (Blood). It starts off as just a ping with an icon (Like bullets for a gun fired), but as you move closer, you get more information, like how long ago the action took place.
It makes you do the work of following the tracks / clues but all of the knowledge of tracking is done by the character, like how could I ever tell how long ago someone walked by, or what type of armor they were wearing without training? It also makes these things pop out to you since your character would have been trained to spot and notice these sort of things.
These sort of mechanics could be insanely good for scouting out enemy zergs, like imagine you're walking through a field when you see like 80 footstep pings, so you walk closer and get the information that they only rode by a minute ago, so you drop a ping in your nodes / guilds discord, "Watch out, large zerg riding through this area."
This could also be very good for tracking down rare mobs, rare roving gatherables (Like super roided out mega sheep with rare pink wool that all of the ladies wanna buy.) and even world bosses if your guild wanted to kill the world boss for that week first.
Good tracking could make rangers insanely desirable for groups / guilds to pick up.
