"The ranger's thing is to survive the world's thing and help other's survive it."
Riffing on this, the ranger could be improved by giving them picks from a menu of nature-themed defensive and utility perks. Surviving is something they don't do too well in the current version, apart from the hunter's high-level trick. I'd like it if Surviving were part of the base class.
For example,
Advantage on poison saves
Advantage on saves vs fey magic
If the party is surprised, pass a DC 15 Dex save to take a single action in the surprise round
Healing poultice
Help self or ally overcome exhaustion
Camouflage (this doesn't really need to be a high-level trick)
Disguise campsite (party invisible during short rest)
