It's difficult to answer your question because it's a little bit nonsensical.
I do not know where you gathered that everyone playing the game was playing ranger or mage.
In term of builds, the game has a lot of leeway and you could beat the game with almost nothing. So I could give you random builds and they would be both unique and workable.
You being a beginner or not in other games doesn't matter much. This game has its mechanics, and you only discover them as you progress in the game (you cannot discover everything toying at level 1, because not everything is unlocked at level 1). There is no alternative to you making your choice, sticking to it and play the goddam game.
It's a little bit like you are asking what flavor of ice cream you should pick, and you are fidgeting for hours around the ice cream truck, smelling around yet not eating any. And you are asking, and asking, then smelling and smelling. It is annoying. I cannot debate much with you about ice cream, as you haven't eaten any yet, just smelled.
