New to the game and still learning which Gods go to which positions in Conquest. Any easy way to tell?

I main only a few characters but I want to start playing Ranked when I hit 30, I'm assuming ranked is Conquest mode. I used to play LoL but it seemed easier to tell who goes where then but not here, especially on console (Xbox).

So I main Ymir, Hel, Nemesis, Erlang Shen, and I want to learn to play a hunter but don't know which.

Any help on where I should go when playing which character? Thanks.
