This is how I feel - for me they don't look good as a mixed force, I'd prefer to see Kruleboyz get some sneaky Gnashtoof cavalry etc rather than go down the road of souping the different styles of Orruks. The Kruleboyz minis so far appeal to me a lot, I could see them ending up being my all-time favourite AoS army (and my biggest AoS spend) if they get a little more unit variety, so I'll keep hoping GW has something more in the works!
In the meantime, I think I'll hop over to Kill Team.
