Maybe the general idea is that rangers are woodland people. Not so suited for dungeno crawling, so it's not a preferred choice.
I 've done different classes in EA, and chose a ranger to embark in the final version. It turned out to be the class I liked most in the game, but it was not the first one I tried.
On tabletop DND, I prefer clerics, and that was my first choice in EA, but in BG3 it's not a very good class to play.
