Spectre do seem to have some odd ideas about starter sets. Simplicity is best.
I think a lot of the stuff in the last year has been a little odd. For a starter pack, I'd have gone for basically matching (two Assault Rifle, AR/UGL, LMG, SMG, DMR) except one guy who could have something special to play around with. I'd think this may be a little more about rotating old stock than actually being a good intro to the rules.
