thoughts on first ever NL army?

Hi all, currently building my first 2000 points NL army (and 1st army ever for me). Not going to play competitive, as I am still fairly new, and wanted a bit of hit and run + heavy weapon support. I am debating whether to use Nemesis Claw as such, or whether to turn them into a mix of Chosen + Legionaries, and using the points for something else. Any comments would be much appreciated. Thanks!
