Finally, they could just add a new subsystem that plays nice with the ranger (such as a proper animal companion rule not tied to familiars or Beastmaster) but again, that doesn't fix the problem with rangers per se and instead is just a band-aid.
I've always liked the idea of giving Rangers a 2nd-level spell that's their equivalent of the Paladin's Find Steed.Finally, they could just add a new subsystem that plays nice with the ranger (such as a proper animal companion rule not tied to familiars or Beastmaster) but again, that doesn't fix the problem with rangers per se and instead is just a band-aid.
Jeremey Crawford spent a little time on twitter dispelling the notion that there would be a completely revised class. And I quote:
"He was referring to the alternative class features we're exploring for various classes, including the ranger. These would be optional rules, not a redesign of a class."

I like that they are thinking a bit more globally than the ranger. I like the idea of them exploring alternate features for various classes. Sounds interesting.

Meh, please. let's at least make the animal companion optional. Lots of people love it, I really don't. Maybe a subclass, except one that works and doesn't suck so all those fine people who do love their animal friends can also have nice things.
The whole preferred enemy thing can go. I'd replace it with something about analyze foe. Let the ranger be a guy who can figure out weaknesses and whatnot in general, rather than just about one group.
