Ok i was figuring i would start another army but im not sure wich army to pick. so far the armys i wont pick are as follow

Necrons(already have played, and there taking a back seat till new codex)
Normal space marines
Chaos daemons(already own army)
daemonhunters
Imperial Guard

Armys i am thinking of

Space wolves (long fangs seem good at ranged, and packs of bloodclaws hiding powerfist are good at range)

Tyranids

eldar (this is iffy, it depends on if my friend stops playing them)
