I would say racast, very tank, has traps that helps a lot with crowd control and has good atp.
Hucast for the same reason plus since his atp is super high you can still do decent damage with no gear, but since it's an hunter and you need to melee is harder to use.
Or you can get a force to start, and support parties till you get gear for other classes.
Just remember that freeze traps are very good.
And try to get a mag with high atp and ata asap. In the beginning is even more important than weapons.
