Maybe but you saidYeah, I don’t think you and I have the same expectations for what a ranger should be able to do.
toYeah, that’s pretty cool.
Which is basically what I'm saying the ranger should be based on.I'm imagining stuff like the old Horizon Walker got. Your mastery of this environment eventually gives you quasi-magical abilities. Maybe you can use the heat of the desert to gain the benefit of blur or gain actual cold resistance due to acclimation to the cold northern lands. Blindsight for those who have hunted in the deep caverns of the Underdark, that sort of thing.
The ranger adapts to fighting in the desert by learning to fight blinded. And in order to make use of it, they commune with desert spirits/fey/ghosts/demons/devils or harvest sand-hearts to blind their foes to even the odds. Which technically isn't fair since the foes aren't trained to fight blind.
